Why not just write a little program that will create a color table with random colors?

Hi Freesurfer Team,

I'd like to view a multicolored quilt of individual cortical icosahedron subdivisions. I have labels for these subdivisions stored in the SUBJECT/label folder I can also batch load all these labels and view them in Freeview but am not sure how to randomize their colors for a multicolored appearance.

I looked up how to use annotation files and tried to amalgate all left cortical labels in the SUBJECT/label/ folder as below:

• cd $SUBJECTS_DIR/$SUBJECT/label
• mris_label2annot --s $SUBJECT --h lh --a leftall.annot

But it asks for a color table file - it seems like editing the Freesurfer color table file will be quite involved.

I have all the labels data and vertices in a w-file - can I use it to somehow create the colortable that I need, or the annotation file itself? Is this the correct way for my goal? Thank you.

Best Regards Pavitra
