====== ExtractEulerAngles.py ======

The script ''timelessExtractEulerAngles.py'' is part of the [[software:timelesstools|TIMEleSS tools]]. It converts results from [[software:grainspotter|GrainSpotter]] to a format which [[software:mtex|MTeX]] can read. Therefore, it extracts the Euler angles (phi1, Phi, phi2) from the //.log// file created by GrainSpotter and writes them into a text file.

<code>
timelessExtractEulerAngles -h
usage: timelessExtractEulerAngles [options] input.log

Reads an indexing log file and generates a set of Euler angles for plotting
with MTex This is part of the TIMEleSS project http://timeless.texture.rocks

positional arguments:
  input                 Path and file name of the indexing log file (required)

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        Output file (.txt file). Default is euler_angles.txt
</code>

The output will be a text file with a list of Euler angles. First column is phi1, second column is Phi, third column is phi2.
