Preserve groupIDs/crysym/... when generating a .tess-file out of an .tesr-file

[schmid02]

Description

I've generated an .tesr-file of an 2-phase EBSD-image containing the phaseIDs in the *group-section and the symmetry cubic in the *crysym-section. So my .tesr-file looks like the output of this:

$ neper -T -n 10 -group "id<=5?1:2" -crysym cubic -format tesr -o ebsd

When I build an .tess-file out of it in the following way, the new .tess-file is missing the *group-section and the crysym is ```triclinic``:

$ neper -T -n from_morpho -morpho "tesr:file(ebsd.tesr)"

My Quick-Fix

I fixed that by providing the groupIDs in a data file, which I loaded with -group "file(groupIDs.txt)" and specifiying the symmetry with -crysym cubic.

Question

But I wondered, is there's a way to read the groupIDs and crysym directly from the .tesr-file?
