Hi Irene,
the label has to shift somewhat in tksurfer, since it will sample it onto the surface. Unless the entire label you drew was exactly on the surface boundary to begin with.

Dear Freesurfers,
I have a problem with labels. I select a given Talairach coordinate that interests me, draw an approximately circular label around it in tksurfer, and save it. When I open that same label in tkmedit, the central Talairach coordinate is changed and the whole label is somewhat shifted. Am I missing something? Should I use mri_label2vol or some other command?
Thanks very much in advance! Irene
