[Freesurfer] converting label files

hello,

i'm trying to take a label that i drew on each subject's surface into volumetric space so that i can extract fMRI parameters within this anatomically defined ROI. i am able to see the label within each subject's orig.mgz volume with tkmedit. however, i'm not sure how to convert this label file into a format that FSL will recognize, given that neither mri_surf2vol, not mri_convert recognize labels as valid input files.

any advice is most appreciated!

thanks, libby
