Hello,

I have a question in regards to the "map label to subjects" feature in Qdec. Basically, I draw and save a label, and then try to map the label to all of the subjects in my SUBJECTS_DIR, but while running mri_label2label, I get this error:

ERROR: there is a vertex in the label that cannot be matched to the surface. This usually occurs when the label and surface are from different subjects or hemispheres or the surface has been changed since the label was created. Label point 7: vno = 166358, max = 163842 command failed: mri_label2label --srclabel /home/bfs-raid1/ryanm/FREESURFER/142_FAE2_blade/v4/freesurfer-from-blade/qdec/lh.parahippocampal_cp

--srcsubject fsaverage --trgsubject 18208 --trglabel /home/bfs-raid1/ryanm/FREESURFER/142_FAE2_blade/v4/freesurfer-from-blade/qdec/lh.parahippocampal_cp --regmethod surface --hemi lh

I have three groups I am trying to compare, 2 proband groups, and 1 control group. So, I constructed separate .dat files and label files for each- one comparing controls vs. group1, and the other comparing controls vs. group2. I seem to be able to run analyses fine on the data, I am just having problems with the "map label to subjects" feature. The order in my .dat files does differ from the order of datasets in my SUBJECTS_DIR, I don't know if this has anything to do with my error.

Any advice/suggestions would be greatly appreciated. Thanks!
