Hello FreeSurfers,

I am trying to run a group analysis with Qdec following this tutorial: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis_freeview

I got a series of errors when I ran: recon-all -s <subjid> -qcache

....

ERROR: number of vertices in /home/subiculum/Desktop/local_recons/OCD_analysis/3662/surf/lh.volume does not match surface (126049,126592)

recon-all -s 3662 exited with ERRORS at Thu Jan 23 15:22:21 EST 2014

One of the errors says "number of vertices in... does not match surface." I found an older post where someone else was complaining about the same error and Doug suggested running "recon-all -surfvolume ..."

I did that and then I ran -qcache again but I got the same errors. It also seems to be a problem with fsaverage. I do have a copy of fsaverage in the subject's directory of this study.

I am attaching the log file with details about the errors.

Can someone help me sort this out?

Thank you,

Mihaela
