Hello,

I guess my main question is are the volume tal coordinates in tkmedit equivalent to the vertex Tal in tksurfer. That is, can I ignore drawing the line in tkmedit and converting with csurf, and just trace out the Tal = 0 line in tksurfer? I think this is what you are implying but just want to make sure.

Also, the cingulate labels are in RAS coordinates. Is there a quick way to convert the Tal=0 coordinate to a RAS coordinate so that I can just divide the cingulate label by applying a condition (eg RAS < x) rather than tracing it out in tksurfer.

Thank you for all your help.

Hi Aviinas,

you could draw the label directly on the inflated surfaces, then use
mri_label2label to map it from one subject (or the average) to the
others.

cheers,
