The input label is one from a set published 1000 brain functional connectivity label from the Buckner lab (Yeo & Krienen, et al., 2011).
No. The first number of all lines are integers ranging from 5 to 132000.
Just adding some details: 1) when we first ran recon did the same label conversion and mri_label2label worked fine. Later we edited the white matter and added control points, and re-ran autorecon2-cp and autorecon2-wm. The surface looked better after the editing, but we have this label conversion problem now.
2) the label conversion ERROR: srcvtno=-1 happens only on one hemi, and mri_label2label haults. However, on the other hemi, although mri_label2label runs through without reporting error, the converted labels on subject surface looks like gibberish and out of place. So it's likely there are problem with both hemis, but with different severity.
Thank you.

what is the input label? How was it created? Does it have -1 as the first number on any line?

Dear Freesurfer list,
I was converting a surface label from 'fsaverage' space to individual subjects and got this error:
###---------------------### Performing mapping from target back to the source label ERROR: srcvtxno = -1 < 0 trgvtxno = 140122, 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 ###---------------------###
The command I used was: mri_label2label --srclabel $fsaverage_brain_label --trg $my_subject_brain_label --srcsubject fsaverage --trgsubject $mysubj --regmethod surface --hemi $hemi
It's worth noting that this subject is from a patient population with lesion and we had to manually edit the white matter and re-run autorecon. This error only happens for one hemisphere of this patient, the other hemi is fine.
Did anyone have this problem before or know how to resolve this? Thank you.
BTW. I found this https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-January/016835.h... in the archive but it was never followed up.
