"Crystal symmetry `triclinic' not supported" error cause.

[nippyawn]

Hello

I want to change the color scheme to IPF.
But, "Crystal symmetry `triclinic' not supported" error happened.
Please tell me how to fix it.

neper -V n50-id1.tess -datacellcol ori -datacellcolscheme ipf -print img10

You did not specify the crystal symmetry while generating the tessellation. There must be the following lines in your tess file:

  *crysym
   triclinic

Change triclinic to cubic or hexagonal in the file, and consider using option -crysym next time.

Thank you! I was able to solve the problem using this method.
