Hi Doug -

Using the overlay threshold flags, I see that the .mgh (yes, the .mg was a cut/paste typo) is in the occipital region and should be frontal, temporal and parietal regions. So, I must be doing something wrong in the mri_vol2surf command:

> mri_vol2surf --src $SUBJECTS_DIR/[subj]/label/LECN_subjXXX.nii --out $SUBJECTS_DIR/[subj]/label/LECN_subjXXX_lh_surf.mgh --srcreg $SUBJECTS_DIR/[subj]/mri/transforms/reg.mni152.2.dat --hemi lh

Plus - as the original ROI encompasses regions in both hemispheres (i.e., the left executive network has a region in the right cerebellum), I thought I would need to repeat this command with --hemi rh?

I assumed I would have to run mris_aatomical_stats on each hemisphere -- after I have labels for the ROI for each hemisphere?

Thanks,

Barbara
