Hi,
I'm running Qdec to gather cortical thickness in specific regions based on the scalar visuals. when I've drawn ROIs over certain areas, I've found "Mapping labels to subjects" would return an error message for certain subjects. There error is as follows:
ERROR: srcvtxno = -1 < 0 trgvtxno = 111070, dmin = 1000 trgregxyz = 0, 0, 0 This means that a vertex in the target surface could not be mapped to a vertex in the source surface because the xyz of the target is outside of the range of the hash table. command failed: mri_label2label --srclabel rh.pos.orbitalfrontal --srcsubject fsaverage --trgsubject DI_April08_filtered --trglabel rh.pos.orbitalfrontal --regmethod surface --hemi rh
Why would this error occur if the surface data in Qdec is based on the averaging of all the subjects? And how can I best go about fixing this problem?
Thanks!
