Command was: mris_make_face_parcellation /cluster/neuromind/douw/scans/controls/nmr00541_FS/surf/lh.inflated $FREESURFER_HOME/lib/bem/ic4.tri native.ico4.annot
Output was: parcellating hemisphere into 2562 units parcellation took 0 minutes and 3 seconds.
I've attached the created .annot for your information.

Hi Linda, I'd need the same type of information, ie what is you mris_make_face_parcellation command line and what is the terminal
output.

Hi Doug, I see. I'm trying to compare fMRI to MEG, so it would be very helpful
if
the same parcellation (i.e. with all 2562 labels) could be used. How
could I investigate why mris_make_face_parcellation skips a bunch of
labels? The problem is not fsaverage5, because doing the analysis in
native space of patients yield the same problem (and the same labels missing). So I guess exclusion of 102 labels always occurs in
mris_make_face_parcellation? Thanks again, Linda On Mon, September 10, 2012 11:27 am, Douglas N Greve wrote:
It looks like there are several (102 to be exact) that do not have any
voxels in your parcellation. Eg, #82:
82 82 ic4.tri_vertex_82 0 So the problem appears to be with mris_make_face_parcellation, not
with
mri_segstats.

also send the summary file?

Hi Doug, I first parcellate fsaverage5 using ico4 (all my functional data
are
morphed to fsaverage5 surface):
mris_make_face_parcellation /fsaverage5/rh.inflated $FREESURFER_HOME/lib/bem/ic4.tri rh.ico4.annot Then I extract the waveforms using mri_segstats mri_segstats --i rh.functional.nii.gz --avgwf rh_ico4.txt --annot
fsaverage5c rh ico4 --sum ico4_rh.sum
