Hi Mudathir,

What freesurfer version are using? I haven’t been able to reproduce this segfault on our end. Can you run the same command on lh.aparc.annot instead to narrow down whether this is an issue with your lh.par.annot file or not?

best

Subject: [Freesurfer] Error with mris_convert

        External Email - Use Caution       

Hi,
I manually made annotation files on an inflated surface of 40 subjects. The labels that makes these annotfiles are 13 in total but not present in all subjects every time, some can be missing depending on the brains surface morphology. I made the ctab files manually in the label folder in eluding an unknown label in the first line. I tried to convert one of the annotfiles into gii format and got the following error:
 mris_convert --annot $SUBJECTS_DIR/spl_01/label/lh.par.annot $SUBJECTS_DIR/spl_01/surf/lh.white ~/Desktop/spl_01/lh.par.gii
reading colortable from annotation file...
colortable with 14 entries read (originally none)
Segmentation fault: 11

What this error exactly means, and how I can solve this issue.
Thanks

Mudathir
