Dear FS experts, I ran surface based PET analysis on subcortical regions. Then corrected the results for multiple comparisons using the method --grf in the command mri_glmfit-sim.
I can visualize the output of multiple comparisons (i.e. the file grf.th1.3.pos.sig.cluster.mgh) on volume using tkmedit, this statistical map shows difference between the groups in the cerebellum.... Instead of visualizing the results on volume, I want to move this file to the cerebellum surface. I already created the cerebellum surfaces from aseg.mgz file in fsaverage using the command mris_tesselate.
How can I move the the file grf.th1.3.pos.sig.cluster.mgh from volume space and map it on the cerebellum surface?
I tried mri_vol2surf but this command requires the flag --hemi as a result it will map the file "grf.th1.3.pos.sig.cluster.mgh" on cerebral hemispheres (lh or rh) but not the cerebellum.. How can I map the file "grf.th1.3.pos.sig.cluster.mgh" on the cerebellum surface?
Thanks for any suggestions, John
