Things can become tricky, however, if you ran series of GrainSpotter indexings as described in the Advanced GrainSpotter indexing section. text/html 2019-12-05T13:09:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://multigrain.texture.rocks/doku.php?id=evaluation:evaluategrainindexing&rev=1575551393&do=diff Graphical assessment of the indexing quality for a given grain Multigrain indexing output files can be tedious to go through. timelessPlotIndexedGrain, which is part of the TIMEleSS tools is mean to help users to visually assess the quality of a grain indexing. text/html 2021-06-24T08:00:40+00:00 Anonymous (anonymous@undisclosed.example.com) https://multigrain.texture.rocks/doku.php?id=evaluation:extractgrainsizes&rev=1624521640&do=diff Determine Grain Sizes The TIMEleSS tools contain two scripts to determine the volume of each grain in the sample. These are timelessExtractGrainSizes.py to obtain relative grain volume and timelessRelToAbsGrainSize.py to convert these relative grain sizes into absolute values. The scripts provide both a list of the grain volumes and a simple histogram of the grain size distribution. text/html 2019-12-05T15:37:40+00:00 Anonymous (anonymous@undisclosed.example.com) https://multigrain.texture.rocks/doku.php?id=evaluation:plotting-grain-orientations&rev=1575560260&do=diff Plotting grain orientations Typically, grain orientations are plotted with MTeX based on the Euler angles of each grain. Extracting Euler angles Extracting a list of Euler angles for the indexed grains can be done using timelessExtractEulerAngles, which is part of the TIMEleSS tools. You will have a list of Bunge Euler angles (using a Bunge convention) as below. You can simply save it in a text file.
