Sorry, I should clarify what I mean by tksurfer crashing: When I define 1000 different colours, only half of the brain gets displayed. I.e. when I click to add the annotation file, it refreshes the image from one side, everything begins as expected, but when it gets to half way across the brain, it seems to runs out of memory and just does not bother displaying the parcellation for that half.
