LaboTex 3.0 - The Texture Analysis Software for Windows

Getting Started

Minimum requirements

To use demo version of LaboTex for Windows, you must have the following: Demo version is very old version of LaboTex - version 2.1 (Release 2.1.012 from April 15th, 2003). Demo version doesn't include many new options from version 3.0 and from version 2.1.013 to 2.1.016 : ODF modelling, determination of volume fraction of texture components by model functions, skeleton lines, misorientation diagrams, ODFs comparison, ODF transformations, ODFs logical functions, pole figure grids etc. (see: 'LaboTex 2.1.015 News', 'LaboTex 2.1.016 News', 'LaboTex 3.0 News') !

The installation of demo version

To install LaboTex demo version (Labdemo2.exe - self-extracting file), follow these directions:
  • Exit any applications you are running.
  • Select 'Run' from the 'Start' menu, find the drive and path with the demo file, then enter Labdemo2.exe, and click 'OK'.

  • Specify a directory to install LaboTex (use short name e.g. LaboTexd in the main directory), then click 'Next'.
  • Verify that the settings are correct, then click 'Next' (or use the 'Back' button if you need to go back and make changes).
  • LaboTex should be installed in the destination directory, and you will be prompted whether or not to view the README file. Click 'Yes'.

Examples for demo tests

Demo version contains 15 examples:
  • Single orientation data (extension SOR):
    • s_orient.sor
  • Pole figure data (extension EPF) - with correction file Cor(5x5).cor
    • C1_Triclinic.epf for C1 triclinic crystal symmetry and triclinic sample symmetry
    • C2_Monoclinic.epf for C2 monoclinic crystal symmetry and triclinic sample symmetry
    • D2_Monoclinic.epf for D2 monoclinic crystal symmetry and triclinic sample symmetry
    • C3_Trigonal.epf for C3 trigonal crystal symmetry and triclinic sample symmetry
    • D3_Trigonal.epf for D3 trigonal crystal symmetry and triclinic sample symmetry
    • C4_Tetragonal.epf for C4 tetragonal crystal symmetry and triclinic sample symmetry

    • O_Cubic.epf for O cubic crystal symmetry and triclinic sample symmetry
    • O_Cubic_C2.epf for O cubic crystal symmetry and monoclinic sample symmetry
    • O_Cubic_D2.epf for O cubic crystal symmetry and orthorhombic sample symmetry
    • O_Cubic_Arb.epf for O cubic crystal symmetry and arbitrary beta range
To select example:
  • Choose 'New Sample' from the menu 'File' or the toolbar,
  • Choose an appriopriate experimental data file (EPF or SOR)
  • Select the correction file (COR(5x5).COR) (only for EPF files)
  • Change sample name (because demo contains calculated CPF file with the same name)
  • Choose 'Create' button and 'Run' button (in the next dialog) to build:
     
    • CPF objects 'HKL' (CPF - experimental pole figures data after correction + initial normalization). As a result you create only CPF objects for the chosen sample (CPF icon will be activated - neighbour icons on the second toolbar are grayed). CPF objects are the basic data for the ODF calculation from pole figures.

      or
       
    • ODF object (in case of the single orientation data SOR). In this case ODF icon will be activated - neighbour icons on the second toolbar are grayed)

The ODF calculation

If a sample contains CPF objects (CPF icon is activated - all samples in the demo version contain calculated CPF objects), you are able to calculate ODF. To do that choose 'CPF to ODF,...' (using menu 'Calculation' or icon on the toolbar). Before begining the ODF calculation you may (using the dialog window from the right side):
  • change optional parameters which will finish calculations (number of iteration steps, minimal RP and dRP errors),
  • add or remove pole figures from the ODF calculations by pressing 'hkl' buttons (ODF is calculated only from visible pole figure(s)),
  • perform appriopriate symmetrizations of pole figures,
  • change upper and lower range of the pole figures selected to ODF= calculation,
  • rotate pole figure(s).
To begin the ODF calculation press the button 'Run ODF Calculations'. The following objects are built at the end of ODF calculation:
  • NPF (normalized experimental pole figures - these figures differ from CPF by normalization factors, NPF are normalized on the base of the ODF),
  • RPF (pole figures recalculated from ODF with 'HKL' corresponding to that one selected for ODF calculation),
  • INV (inverse pole figures (XYZ) : (100), (010), (001)).
You can see that sample contains new objects which are symbolized by activated icons on the second toolbar: ODF, NPF, RPF and INV. You can calculate next ODF for the set of new parameters. In this case a new job will be created (on the second toolbar will be displayed new buttons 'J1', 'J2' ...). For one sample you can have maximal 9 jobs.
 

The ODF symmetrization

You can do a symmetrization of calculated Orientation Distribution Function (ODF) to a monoclinic, orthorhombic or axial sample symmetry. This option can be selected from the 'Calculation' menu or by pressing the appropriate icon on the toolbar.
 

APF and INV calculation

You are able to calculate additonal pole figures (i.e. pole figures, which were absent in the ODF calculation) and inversion pole figures when the sample contains calculated ODF (in that case ODF icon is activated). Choose 'ODF to APF' or 'ODF to INV' (using the 'Calculation' menu or icon on the toolbar) to open dialog for APF and INV calculations.

Display of different type of the LaboTex objects - Compare Mode

Labotex operates on six types of the LaboTex objects:
  • CPF - Corrected Pole Figures
  • NPF - Normalized Pole Figures
  • RPF - Recalculated Pole Figures
  • APF - Additional Pole Figures
  • INV - INVerse pole figures
  • ODF - Orientation Distribution Function
These six types of objects can be stored in three types of containers:
  • The Pole Figures Container for CPF, NPF, RPF, APF objects (yellow colour icon)
  • The Inverse Pole Figures Container for INV objects (blue colour icon);
  • The Orientation Distribution Function container for ODF objects (green colour icon).
The toolbar with objects is displayed on the top of the application window, below the Main Toolbar. The toolbar provides quick mouse access to the LaboTex object (selecting: hkl - for pole figures, XYZ - for inverse pole figures and type of projection for ODF). Number of objects in the containers are indicated in the left bottom corner of the window ( yellow colour number for pole figures container, blue colour number for inversion pole figures and green color number for orientation distribution function container). Only one projection can be in the container of the ODF objects simultaneously. For the ODF container, the number indicates the number of 2D ODF sections. Pole figures type objects (CPF, NPF, RPF, APF), inversion pole figure type objects (INV) and orientation distribution function (ODF) type objects can not be displayed in one window simultaneously. You can display different type objects using 'Compare Mode' (using 'View' menu or icon on the toolbar). In the compare mode you can work in two windows using different or the same type of objects. In this mode following options are not active:
  • calculation (ODF, APF, INV);
  • creation of new sample (CPF);
  • quantitative analysis.

Orientation analysis

You can do orientation analysis for pole figure objects (CPF, NPF, RPF, APF) and ODF objects. You can not do analysis for inversion pole figures objects. For different type of objects (PF and ODF) you have to use 'Compare mode' (using 'View' menu or icon on the toolbar). The Compare mode is very important for education (interdependence of orientations on PF and ODF).
Choose 'Orientations Analysis' from menu 'Analysis' to begin analysis. Cross marks indicate positions of orientation. On the second toolbar you can see orientation in HKL UVW and Euler angles. Using buttons from the second toolbar, you can move cross mark(s).
You may write angles or indices of orientation directly into the text windows on the toolbar.
On the ODF projection you may click on the diagram that moves a cross mark and shows appriopriate orientation.
To see the value of intensity for the selected orientation (indicated by cross marks on ODF or PF diagram) you can select 'Show PF or/and ODF Value' (using 'Analysis' menu or 'V' icon on the toolbar) . Value of ODF or/and PF (see help) are displayed on the status bar (sums PF value(s) or/and ODF value in cross mark(s) position(s), for more than one of PF objects - average of sums).
Attention ! In orientations analysis mode '3D View' is not active.

Qualitative Analysis

To do qualitative analysis, choose appriopriate objects and next press 'SORT' button on the bottom toolbar or 'Sort of Orientations from Database' using 'Analysis' menu. You will see the window with assorted orientations from database by PF or ODF values (+ one additional orientation for current cursor position).
You can also analyse near (HKL)[UVW] orientations. Select "Orientation analysis". Click right mouse button in selected point on the pole figure or ODF projection. This option can be chosen from analysis menu too. "Near orientations" can be sorted by PF or ODF values, Miller indices or distance,

Quantiative analysis

Quantitative analysis is possible only in a single mode for selected ODF projections.
Quantitative analysis makes possible to calculate volume fractions of chosen set of texture components.In order to complete the quantitative texture analysis, the following steps are recommended:
  • display one of ODF projections,
  • identify the texture components (showing orientations from database and/or identifying orientations components by manual movement of the cross mark),
  • select 'Quantitative Analysis' from 'Analysis' menu or press '%' icon on the toolbar
  • select texture components (orientations) for integration of volume fractions
  • select the integration width (change slider position) of each Euler angle for selected components
  • press 'Calculation of volume fraction of texture components' button

Orientations type database

You can add orientations to the database selecting 'Orientations Type Database' from the 'Analysis' menu .
It allows to edit or delete orientations from database.

Calculated example

The sample O_Cubic.epf contains the following calculated objects:
  • CPF (experimenatal corrected pole figures);
  • ODF (orientation distribution function);
  • NPF (normalized experimental pole figures);
  • RPF (recalculated pole figures from ODF);
  • INV (inverse pole figures).
If you choose O_Cubic sample using 'Open sample' from the 'File' menu or icon on the toolbar then on the second toolbar there should be activated icons of CPF, ODF, NPF, RPF and INV objects. Select one of them and display the appropriate object by pressing one of the activated buttons respectively.
For other examples containing pole figure data (CPF), you may calculate the ODF (and NPF, RPF, INV simultaneously). CPF objects can be recalculated (with changed sample name if you wish) from experimental data (EPF object).

3D View

You can view objects in 3 dimensions choosing '3D View' from 'View' menu or '3D' icon on the toolbar.
This option is available for main window only.

Objects description

Clic the right mouse button to view of objects descriptions.

Selected object

Click the left mouse button to select an object. Selected object is in red a frame and appriopriate button contains red text. If current sample is different than selected object sample, the LaboTex changes current sample. You can delete or magnify selected objects. Mmagnify an object by clicking twice on it (in ODF you can magnify one section of the projection).

Show of basic region of PF

Basic region means:
  • half circle of PF in case of monoclinic sample symmetry,
  • quarter circle of PF in case of orthorhombic sample symmetry
  • 2D radial section of PF in case of axial sample symmetry.
In this mode orientations analysis in not active!

LaboTex Version 3.0 (version available from September 2005)

News in version 3.0.02.

In version 3.0 of LaboTex you can find many tools for comparison of ODFs (up to 12 ODFs) and for comparison of pole figures (also up to 12 pole figures).
  • ODFs comparison (Screen Shot):
    • ODF line sections (cuts) - user define two points in Euler Space (Screen Shot). LaboTex shows ODF intensity along section defined on the base these points. User can also choose initial points from orientations database (when click on the 'Start Point' or 'End Point' button database is available (Screen Shot) ). Comparison up to 12 ODFs is possible, (Screen Shot)
    • skeleton lines (Screen Shot). - user can create such diagrams as: alpha-fiber, beta-fiber, gamma fiber etc.. User can choose skeleton lines on the base of Euler angle (Phi1, Phi or Phi2) and:
      • maximal intensity ;
      • integral intensity.
      User can also change ranges in which LaboTex looking for maximal odf value or made integration (from +/-2 to +/-20 deg). User can make comparison up to 12 of skeleton lines;
      Examples (3 skeleton lines):
      Options: 'No fill', 'All black' (for black and white paper) ;
      Options: 'Fill'.
    • misorientation histograms.(Screen Shot) User define start point in Euler Space from which LaboTex shows misorientation diagrams. Misorientations diagrams are calculated on the base of ODFs in range 0 to 80 deg from start point (start orientation). LaboTex shows intensity which is the releative intensity i.e.intensity relate to intensity of random sample (I=I(sample)/I(random sample)) for the same range of misorientation angle. User can make comparison up to 12 misorientations histograms. User can also change histogram step in range 1 to 10 degrees;(Screen Shot)
    There are many options to optimalize quality of diagrams :
    • scale (in percent of maximal intensity value: 0.1 up 100%) (Screen Shot);
    • colors (defined by user);
    • types of lines (14 types with different dots+solid) (Screen Shot);
    • line options (all solid, all black, black countours) (Screen Shot);
    • width of lines (0 to 10 pixels) (Screen Shot);
    • fill.
    User can also save current parameters and/or samples (Screen Shot). The first ODF is current ODF. Next ODFs for comparison user can choose using appriopriate comboboxes and buttons on the tools window from right side. (Screen Shot);
  • ODFs - logical operations. (Screen Shot) For activate this option user should switch LaboTex to Compare Mode and next choose two ODFs for comparison: one in left window and second in right window (LaboTex Compare Mode). On the base these two ODFs (A - from left window and B from right window) LaboTex creates new ODF which is:
    • intersection of ODF A and ODF B,
    • diference of ODF A and ODF B (or B-A),
    • union of ODF A and ODF B,
    • sum of ODF A and ODF B,
    • ODF difference : A or B - intersection A and B,
    • inverted ODF (only for A).
    New ODF is created in new Job for sample of ODF A. You can copy and paste these diagrams to other applications or you can made images in 'BMP' ot 'TIF' format (menu 'Edit').
  • Transformations of ODF. LaboTex calculates new ODF which is results transformation of initial ODF. New ODF is created in new job for sample of initial ODF. There are two kinds transformations:
    • frame rotations, (Screen Shot). - user can rotate sample frame. This option is very important if user would like to see ODF for other (different) sample position (for example if you want see ODF for the perpendicular surface with relation to surface which was measured you should transform initial ODF about Phi=90deg). User can create change sample symmetry for new ODF.
      Example:
      Initial ODF (3D Image) - Cubic ,
      Initial ODF (ODF with Cubic orientation) - after transformation of frame (45 degrees, Phi axis) gives ODF with Goss Orientation .
    • builder of model rotations, (Screen Shot). (crystalites/planes rotations). In first step you build rotation model and save it. In rotation model you can choose up to 10 orientations for which you set:
      • ranges of Euler angle around center of orientation (and for symmetrically equivalent positions);
      • vector "hkl" around which will be rotate crystalites/planes (only these which are included in ranges chosen by user);
      • rotation angle;
      • recent of rotated crystalites/planes (from 0 to 100%).
      In second step you choose rotation model and make ODF transformation (Screen Shot).
  • Generation of single orientations (Screen Shot) : LaboTex creates set of single orientations on the base of current ODF. User can choose number of single orientations from 10000 to 9999999. This option is important for user which modelling deformation (VCS users) etc.; User can also generate random set of single orientation using this option. SOR file creates by LaboTex user can input as a new sample and he can make ODF calculation.
    Examples:
    ODF creates on the base set of 500,000 single orientations generates with 'Random' option. (Screen Shot).
    Section of pole figure {111} calculated on the base above 'Random' ODF. (Screen Shot).
    Comparison pole figure for real texure free (random) sample (red) with pole figure generates from 'random' ODF creates on the base set of 500,000 single orientations (blue) (Screen Shot).
  • Pole figures sections (cuts). User defines start and end points on the pole figure and Labotex shows intensity along this section (Screen Shot).
    There are following cuts available: LaboTex shows position of section line on the pole figure when button 'View' is pressed (Screen Shot). Up to 12 pole figures can be comparised. All information about comparised PFs are displayed in infor window from left side (Screen Shot).
    All pole figures which section are displayed have to be choosen before button '2D' has been pressed. (if you choose more than 12 pole figures then LaboTex shows only first 12 pole figures sections). There are many options to optimalize quality of diagrams :
    • scale (in percent of maximal intensity value: 0.1 up 100%) (Screen Shot);
    • colors (defined by user);
    • types of lines (14 types with different dots+solid) (Screen Shot);
    • line options (all solid, all black, black countours) (Screen Shot);
    • width of lines (0 to 10 pixels) (Screen Shot);
    • fill.
    You can also save current parameters (Screen Shot). You can copy and paste these diagrams to other applications or you can made images in 'BMP' ot 'TIF' format (menu 'Edit').
  • On-line view of alpha (radial angle), beta (azimuthal angle) and pole figure value in mouse cursor position. LaboTex display this data in format: (alpha,beta) PF='value of PF'. Only in case, when mode of LaboTex is switched to 'Cursor Analysis' and toolbar button 'Show Value(s)' is pressed LaboTex shows of sums PF value(s) in pole positions which are indicates by cursors (mark by small crosses) (for more than one of PF objects - average of sums). ; (Screen Shot)
  • New column in "Near {HKL}< UVW>" window has been added: column with misorientation angles (misorientation beetwen {HKL}< UVW> and cursor position on the ODF diagram). (Screen Shot).
  • User defined grid for pole figures. User can define grid for alpha angle and/or grid for beta angle of PF.
    (Screen Shot - Dialog);
    (Screen Shot - Pole Figure with grid /option 'Cross'/);
    (Screen Shot - Pole Figure with example of grid);
  • added several new data formats (for input data in these formats please see on the WWW page : LaboTex Formats:
    • 'NJA' - Seifert ASCII data format (compatible also with data from PSD)
    • 'NJC' - Seifert binary data format (compatible also with data from PSD)

  • Option "Once" in volume fraction calculation is active now (calculation of relative error between model ODF and experimental ODF).
  • New option has been added as default: "Max. linearity" in calculations of a model ODF. LaboTex chooses orientation (among sym. eq. orient. of component) for model building which lies in maximal linear area of ODF. This option is essential only for cubic crystal symmetry.
  • Corrected bug in volume fraction calculation (integration method) - volume fraction for components with sym. eq. orientations lying on phi=0 (for example: Cube) was elevated when there were also other components with sym. eq. orientations lying close phi=90.
  • Option "User defined .." in menu Edit for skeleton lines plots is grayed now.

LaboTex Version 2.1.015E news (10.2003)

  • Model function method determination of volume fraction of texture components (texture approximation by model components).
    Screen Shot - Model Function Method - Dialog Window
    Now, you can in LaboTex make calculations of volume fraction of texture components using two independent methods:
    • integration method;
    • model function method.
    Model function method is very helpful for analysis of texture with overlapping components. After calculation you can simple compare experimental ODF with calculated:
    Screen Shot - Model Function Method - Compare experimental and calculated ODF
     
  • Modelling of ODF, pole figures and inverse pole figures. Now you can very easy create of a model ODF.
    You can choose:
     
    • Crystal Symmetry;
    • Sample Symmetry:
    • Grid cells for output ODF.
    and next you can choose one or more components (up to 10 components). For each texture component you can choose:
    • volume fraction;
    • FWHM for each Euler angle (phi1, phi2 and phi);
    • distribution (Gauss or Lorentz).
    Screen Shot - Modelling of ODF - Dialog Window
    Screen Shot - Modelling of ODF - Example of calculated ODF
    Next (from a model ODF) you can create any model pole figures or/and any model inverse pole figures using appropriate dialog for create of APF (additional pole figures) or for IPF (inverse pole figures).
  • Visualization of background and manual setting of background (fon) in volume fraction calculation (Integration Method). In previous versions of LaboTex, LaboTex set up value of background to minimal value of ODF in integration method of volume fraction calculation. Now, minimal value of ODF is set up for default only and user can change this value.
    Screen Shot - visualization of background and manual setting of background
     
  • The possibility of accommodation of a plot convention for pole figures. The choice among different conventions you can find in "LaboTex Options" ----> "LaboTex Conventions". You can choose start plot pole figures from "N","E","S" or "W".
    Screen Shot - Plot convention for pole figures - default setting
    Screen Shot - Visualization of pole figure in default plot convention
    For example: if you would like plot pole figures with rolling direction "RD" in "E" you should choose in "LaboTex Conventions" start plot pole figures from "E"
    Screen Shot - Plot convention for pole figures - start from "E"
    and next you should change description of Y axis to "RD" in "Captions and Draws" (LaboTex Options). Please also delete old description of X axis.

    • counter-clockwise;
    • +90 deg pole figure rotate;
    • +180 deg pole figure rotate.
    Screen Shot - The choice of registration convention for pole figures
    You can use this option also when you incorrect install sample in the goniometer, receive sample from laboratory using other convention etc.
  • Now, for each available format of pole figures you can set up registration convention for default ("LaboTex Options" ----> "LaboTex Data Format").
    Screen Shot - Pole figure registration convention - permanent setting
     
  • New options for input data: When background data of pole figure is greater than pole figure data for some values LaboTex makes:
    a) negative values of pole figure after correction for background are set to zero.
    b) adds to all pole figure data absolute value of the lowest values of pole figure after correction for background (LaboTex makes all data positive); User may choose option a) or b) in "LaboTex Option" ----> "Data Formats". Default is option a).
    Screen Shot - The choice of option for background of pole figure
    Now, LaboTex informs user's when it finds data for which background data are greater than pole figure data and LaboTex display percent these data (Example).

    • Normal (color filling and isolines are in the same color) ( Example );
    • Black (color filling and black isoline) ( Example );
    • White (color filling and white isoline) ( Example );
    • Continuous (color filling in function of PF, INV/IPF or ODF values, no isolines) ( Example ).
  • New option: grayscale in 3D visualization.
  • Filling pole figures when are presented in basic region.
  • WARNING: LaboTex has and ever had user defined legend. Default is "Automatic". User may change to "Manual" or to any user defined files with isoline values. For example and details see to "Determination of Volume Fraction of Texture Components Using LaboTex" manual. User can save in every time current isolines . It is very important compare objects the same type for the same set of isolines.

LaboTex Version 2.1.011 news (17.01.2003)

  • New data format "NJA" - Seifert ASCII data format. Each pole figure and background file has to be in separate file with extension NJA.Pole figures data files are input from "Choose Experimental Data" list and defocussing correction data (random pole figures data) can be input if necessary from "Choose Defocussing Correction" list. 'NJA' files contain background data (additional files with background data are unnecessary).
  • The possibility of the evaluation of parameters of component peak. New slider in Quantitative Analysis which allows magnification of component peak and manually evaluation its parameters (heights, FWHM...).
  • Labotex can read background files for UXD format: data for background please mark with 'B' letter in indices of pole figure ( in filename - for example '<111B>corund'). LaboTex requires one pole figure on the one UXD file. Each pole figure and background file has to be in separate file with extension UXD.For example: sample_100.UXD, sample_100BL.UXD, sample_100BR.UXD, ... (files with terminations BL or BR are background from 'left' and 'right' side of PF. LaboTex average BL and BR values). You may use only BL or BR file, too. Background files in UXD format are allowed only one background value for one alpha value.
  • Fix problem with symmetrically equivalent orientations for some fiber components. For example: for component <511>fiber LaboTex shows only <511>fiber and <151>fiber sym. eq. Now LaboTex shows all symmetrically equivalent orientations: <115>fiber, <511>fiber and <151>fiber.
  • Extended format for display value of isoline and maximal value of ODF. Now it is long enough even for very sharp textures.
  • Fix problem in compare - high resolution mode with display ODF values.

LaboTex Version 2.1.009a news (11.10.2002 - extended version 2.1.009)

  • New options in calculation of volume fractions.
    Calculations of volume fraction of chosen texture components are performed by integration around those components in basic region. Each components can be represented by more than one symmetrically equivalent position (orientations) in basic region.
    Fundamentals for calculation of volume fraction of texture components:
    • LaboTex makes integration around each orientation in the ranges delta chosen by the user for each Euler angle:
      • Phi1-delta(Phi1) to Phi1+delta(Phi1),
      • Phi-delta(Phi) to Phi+delta(Phi),
      • Phi2-delta(Phi2) to Phi2+delta(Phi2),
    • In the case of exit outside the basic region of ODF space (Euler angles space) LaboTex continues integration in equivalent area of the basic region.

    The overlapping problem
    The overlapping problem appears when integration ranges (delta) are too wide or when orientations are near each other in Euler angles space. Integration area of texture components can be overlapped in two ways:
    i) Overlapping of integration ranges between symmetrically equivalent positions of component
    ii) Overlapping of integration ranges between different components

    LaboTex gives three different abilities (strategy) to solve problem of overlapping of integration ranges between symmetrically equivalent positions of component (case i) :
    • "Simple Integration" - overlapping region is multiply integrated. Integration around any single component in full range of basic region gives (100% minus background)*number of symmetrically equivalent position.
    • "Singlely Counts in Overlapping Area" - overlapping region is only singlely integrated for component. Integration around any single component in full range of basic region give 100% minus background.
    • "Divide by Number of Symmetrically Equivalent Position" - LaboTex integrates for all symmetrically equivalent positions of the components with proper weight equal 1/number of symmetrically equivalent positions. Integration around any single components in full range of basic region give 100% minus background.

    To solve problem of overlapping of integration ranges between different components LaboTex offers (case ii):
    • Total percent of overlapping (overlapping volume fraction) is displayed in special window ("Orientations Overlap"). Overlapping volume fraction can be limited by diminishing integration ranges of texture components.
      • In case of "Simple Integration" overlapping volume fraction means sum of overlapping between different components and between symmetrically equivalent positions of all overlapped components.
      • In case of "Singlely Counts in Overlapping Area" overlapping volume fraction means sum overlapping between different components.
      • In case of "Divide by Number of Symmetrically Equivalent Position" overlapping volume fraction means excessive orientation overlap. Excessive orientation overlap area is defined in the points where sum of weights is greater than 1. The weight is equal to 1/number of symmetrically equivalent positions. Excessive ODF value in given point is equal to the product of the ODF value and sum of weights minus 1. The volume fraction of excessive orientation overlap is the integral of excessive ODF values in mentioned area.
    • Overlapping volume fraction can be divided among overlapping orientations. This option causes the division of ODF values from overlap areas among overlapping orientations:
      • in case of "Simple Integration" and "Singlely Counts in Overlapping Area" ODF values in overlapping areas are divided proportionally to number of symmetrically equivalent overlap orientations.
      • in case of "Divide by Number of Symmetrically Equivalent Position" excessive ODF values in overlapping areas are divided among components proportionally to the weights and to number of symmetrically equivalent overlapping orientations.
  • Fix problem with false information about not enough free space on the disk.
  • Fix problem with UXD files.
  • Now LaboTex shows minimal and maximal value of objects (PF,INV and ODF) separately for left and right window in the Compare Mode.
  • Improved the refreshment of the screen after the change of colours in the Compare Mode.

LaboTex Version 2.1.006 news

  • LaboTex convention for sample and crystal coordinate system - from version 2.1.006 (change important in Euler to Miller conversion and Miller to Euler conversion for symmetry lower than cubic symmetry):
    • 1) X,Y,Z axis perpendicular to each other,
    • 2) [100] axis is in XZ plane,
    • 3) Z axis is paralel to the [001] crystallographic plane,
    • 4) Crystal coordinate system and sample coordinate system should be at the same order i.e. both right-handed or both left-handed,
    • 5) Bunge definition of Euler angles.
  • Now, LaboTex shows exactly and approximately orthogonal vectors {HKL}< UVW> for indices lower than 15 (eliminates "Non orthogonal" information). Conversion Euler angles to Miller indices is made on the basis of cell parameters of sample (in compare mode - on the basis of cell parameters sample from active window). If pole figures in active window have different cell parameters conversion is made on the basis of cell parameters of sample which pole figure is first in active window.
  • Now basic area for pole figures is equal to a full range of Euler angles hence number of orientations in basic area (in combo box) can be different for ODF and PF objects.
  • The window for set up {HKL}< UVW>.indices has been changed. Now you can see for active window: cell parameters, orientation type (Euler angles and Miller indices), basic region, orientation(s) in basic region (Euler angles and Miller indices).
  • New samples for hexagonal symmetry
  • Fix error in "Copy to clipboard" in low resolution
  • Fix error in save isolines (for isolines > than odf-max or pf-max)
