or you can convert the label to a mask, then run mri_mask on he sig.nii.gz file, then view it in tksurfer. Bruce's suggestion is probably easier. doug

Hi Resa

you can create a label of the region you are interested in and use the mask_label command on the tcl prompt when running tksurfer.

Hi,

Using anatomical parcellation, I have labels for the occipital and temporal lobes in my subject. I have a functional map in the same subject that I want to show the activity only in the occipital and temporal cortex, and I want to mask the activity in the other parts of the cortical surface. How can I do this with FS-FAST/Freesurfer?

Thanks, Reza
