[Freesurfer] A potential problem in qdec

Dear Freesurfer users,

Is there anyone that use virtual box freesurfer version for group comparison via qdec? I use the freesurfer version below: VirtualboxXubuntu 12.04stable v5.3.015 Aug 2013freesurfer-Virtualbox-linux-x86-stable-pub-v5.3-full.vdi.gz9.0G

I used qdec for group comparison, but there was an error (acctached error.png) that puzzled me for a long time. I and my colleague help me to check all the files but do not find where is the error. However, if I remove the files gender.levels, group.levels and fsid.levels (I means that I just keep the qdec.table.dat), it works. I can design, display and finally obtain the results.

Could anyone give me some suggestions?

Any help would be greatly appreciate.

Best, Feng
