Dear Freesurfers,

I am trying to obtain clusters of vertices whit a certain value over a threshold inside a lesion mask projected to the surface, with the command:

mri_surfcluster --subject MS075_R01_07_R1year --hemi lh --in lh.MS075_R01_07_R1year.subjspace.mgh --surf lh.pial --mask lh.surf_magn_CL02_fwhm1.mgh --thmax 49.95807 --thmin 1 --sign pos --minarea 0.01 --sum summary.txt

But I obtain this result saying there are no vertices in my mask.

thsign = pos, id = 1

srcsubjid = MS075_R01_07_R1year

srcsurf = lh.pial

srcframe = 0

thsign = pos

thmax = 49.9581

subjectsdir = /autofs/space/alicudi_002/users/mscat/users/caterina/3T/recons_fsv5.3

FixMNI = 1

Found 0 vertices in mask

Can you help me figure out why?

Thanks,

Vale
