This is Doug's response to my question. It might be also relevant to your question.
Reza ************************************************** Not directly. tkmedit is a volume viewer, and the spherical maps are of course on the surface. You can take your .w files and stuff them back into the volume with mri_surf2vol. doug Reza Rajimehr wrote: > Hi, > > Is there any way to visualize spherically-averaged maps in tkmedit-sess? > Currently, it seems that tkmedit-sess only accepts -space native or tal. > > Thanks, > Reza ************************************************** > Hi FreeSurfers, > > A small group analysis question of fMRI data (fixed effects).
