ORTools v2.3.0

This new release features various minor improvements. Especially the plotting capabilities for variant pairing analysis and habit plane determination, demonstrated in Examples 9 and 10, have been improved considerably.

To enjoy all the features provided with this release v2.2.0, please pair up this toolbox with MTEX 5.10 or later

Habit plane determination:

The tools for habit plane analysis, showcased in Example 9 of the previous release have undergone major revision. Now all methods for trace determination that were reported in the accompanying research paper are supported in the function computeHabitPlane.m. Furthermore several additional plots were added, which now allow for a better visual inspection of the results. The example demonstrates plots of all fitted traces and the traces that are projected based on the fitted habit plane. Also the spherical projection plots were revised to give a better indication of the sensitivity of the analysis.

Variant pairing analysis:

The previously implemented analysis for block boundary pairing, or variant pairing, is now generalized in a new function computeGrainPairs.m. The functionality is demonstrated in Example 10 where different types of analysis are presented alongside scientific references. Some standard types of analysis are demonstrated and it is also demonstrated how the analysis can be customized according to individual applications.

Compute variant grains:

The function computeVariantGrains.m now refines the child grains in the "job" object based on their variant IDs while keeping the grains of the remaining phases untouched. The ebsd dataset is returned with updated grainIds associated with the refined grains. Previously this function only returned data of the child phase.

Habit plane determination:

With the successful development and release of the habit plane calculation in MTEX 5.9, we introduce Example 9 to ORTools showcasing the function computeHabitPlane.m.

Bain group determination:

With the successful development and release of the Bain group calculation in MTEX 5.10, we introduce the functions computeBainGrains.m, plotMap_bain.m, and plotPDF_bain.m to ORTools to enable Bain group analysis.

New colormaps:

With the integration of Perceptually uniform colormaps for MATLAB into ORTools, users now have the ability to plot their data using 74 additional colormaps.

Numerous minor functional and speed improvements, and bug fixes:

• The odfs exported by orientationMaker.m and fibreMaker.m are saved as lossless *.mat file objects.
• The odfs imported and exported plotPODF_transform.m are saved as lossless *.mat file objects.
• Unless specified otherwise by the user, the transformed child odf in plotPODF_transform.m is created using the modal volume fractions of parent orientations as default.
• Improvements to Example 4 further showcasing the transformation texture capabilities of ORTools.
• Addition of Bain group analysis to plotStack.m.
• Defining colormaps directly by their file name and not as a string.
• Many more bug fixes and speed improvements.

v2.0.2 - New release

Several minor bug fixes.

v2.0.2 - New release

This new release features several minor bug-fixes.

v2.0.0 Variant graph approach and advanced variant analysis in steels

We are happy to announce the release of ORTools v2.0.0.

With the successful development and release of the variant graph approach to parent grain reconstruction in MTEX 5.8, we introduce a new Example 7 for ORTools. In this example, we demonstrate how to use the variant graph approach with ORTools and introduce a list of further new features for advanced variant analysis for lath martensitic steel microstructures:

• Grain refinement at the variant level (computeVariantGrains)
• Variant pairing (block boundary) analysis (plotMap_variantPairs)
• Block width measurement contributed by Dr. Tuomo Nyyssönen (plotMap_blockWidths)

All of these advanced variant analysis features can be applied to the entire dataset (map), or to individual prior austenite grains, either by specifying the parent grain ID or within the interactive function grainClick.m.

v1.2.0 Tabbed figures and minor changes

- Suitable with MTEX version >= 5.7
- Example 5 is currently not working with MTEX v5.7.0 but works with MTEX Developer v5.7.1.

• When multiple figures are outputted from a single ORTools plot function, they are now arranged in multiple tabs within a single figure window.
• "grainClick", when used in conjunction with "plotStack", features a table output of variant and packet Id statistics.
• "plotPODF_transformation" was renamed to the shorter "plotPODF_transform".
• Minor changes were implemented on several functions.
• The examples were improved.

v1.1.3 Minor improvements

Compatible with MTEX 5.7.0

• Compatibility down to MATLAB 2016b ensured in alignment with MTEX
• Added minor features and additions
• Minor updates of the examples

v1.1.2 including a new Example 6

• We have added a new example 6 on 2-stage reconstruction of transformation microstructures in TWIP-TRIP steels.
• Minor changes and bug fixes were also implemented.
• Due to a minor issue with the latest version of MTEX 5.7.0, Example 5 may not work correctly. If it is important to you, install the latest MTEX developer branch or wait for MTEX 5.7.1.

ORTools v1.1.1: Compatibility with new syntax in MTEX 5.7

• ORTools v1.1 still contained some compatibility bugs related to the new syntax in MTEX 5.7. These bugs should be fixed in this release.
• All examples were updated to be compatible with the new MTEX 5.7 syntax. Some details may be different from those presented in the instructional videos.
• Code cleanup and minor fixes were made to auxiliary functions.

Additional features were added:

• Plotting of both parent-2-child and child-2-child disorientation angle distributions with "plotHist_OR_misfit".
• Options to remove the outline box and scale bar from the plots of "grainClick.m" and "plotStack.m". This is demonstrated at the end of example 1.
• Packet PDFs can now be plotted using "plotPDF_packets.m". This is a standard figure in "plotStack.m" as well.
