Thanks, Chris. I will definitely install SurfIce and try this out

I have looked through the script. Couple of followup questions:

I see I will have to append my coordinates with the fields 'Clr' and 'Sz'.

1. Is there somewhere in SurfIce documentation or code that lists what the numbers corresponding to different colors are (e.g. 1=red, 2=blue etc)?

2. Does 'Sz' correspond to mm or voxels or.....? i.e. what does Sz = 1 mean?

Thanks,
Nina
