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?
Best regards, Mohamed

Hi Mohamed, please remember to post to the list. As for your question, what aparc files are you looking at? Those measures are in, eg, lh.aparc.stats

Dear Douglas,
Many thanks for your answer!
We are interested on one region belonging to the Brodmann areas "Perirhinal". Cortical thickness as well as volume values appear on the BA stat list and not on the aparc or aseg lists. Does the ROI-based analysis could be used for this BA region?
Best regards,
Mohamed

Do you just want to do an ROI analysis? Or do you want to do a voxel-based analysis? If ROI-based, then follow the steps on the ROI tutorial (ie, aparcstats2table and mri_glmfit with --table input).

Hi Mohamed
Doug is away this week and can give you a more details answer next week. Certainly you could use mris_anatomical_stats -l <BA label file name> to compute the volume/thickness/area for each subject then do whatever GLM analysis you want outside of FS.
cheers Bruce

Dear Freesurfer users,
I would like to study the between groups changes of volume/cortical thickness of one region (Perirhinal) belonging to the Brodmann areas. I tried to do that with Qdec tool but unfortunately Qdec does not load the Brodmann areas stat list. I am wondering if I could use the GLM formalism with of course regressing out the ITV. Any suggestion/advice will be very welcome.
Many thanks in advance,
Best regards,
Mohamed
