Dear Douglas, Thank you very much for you answer. I checked all the aparc stat files (/Freesurfer/subjects/subjectID/stats/lh.aparc.stats; lh.aparc.a2009s.stats ....) and my region of interest "perirhinal" (region extending on BA35 and BA36 areas) is only present on the lh/rh.BA.stats files (/Freesurfer/subjects/subjectID/stats/lh.BA.stats and rh.BA.stats). I use Freesurfer version 5.3. When using Qdec tool the only uploadable files are .aparc files. Is it possible to upload also the regions of BA.stats files?

As for your question, what aparc files are you looking at?
