External Email - Use Caution Thanks a lot Doug,
I started to proceed with FS group analysis wiki you sent to me. Accordingly, i have to resample all my data (output of recon-all for a given subject for example) into fsaverage using mris_preproc. My commandline for a subject was: mris_preproc --target fsaverage/ --hemi lh --s FSP010/ --out lh.FSP10.white.mgh --meas white and i got the error: Reading source surface reg /usr/local/freesurfer/subjects/FSP010//surf/lh.fsaverage/.sphere.reg No such file or directory mri_surf2surf: could not read surface /usr/local/freesurfer/subjects/FSP010//surf/lh.fsaverage/.sphere.reg No such file or directory As there was no lh.fsaverage/.sphere.reg folder, i found one file in fsaverage/surf: lh.fsaverage_sym.sphere.reg. i created a folder with the name lh.fsaverage and i copied/pasted the mentiomed file into this folder and i changed the file name to: ./sphere.reg. I got the error: Reading curvature file /usr/local/freesurfer/subjects/FSP010//surf/lh.sphere MRISreadBinaryCurvature: incompatible vertex number in file /usr/local/freesurfer/subjects/FSP025//surf/lh.sphere What is the problem with my mris_preproc command-line?

Use the command line stream (mri_surf2surf, mri_glmfit, mri_glmfit-sim). https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis > > > 2- should i input all patients and controls surfaces in standard > surface before entering to Qdec? > > > 3- I would like to resample whole cortex (whole cortical thickness, in > other words: the average of all projfrac between 0 and 1), is it > possible? or i am limited to resample one given depth of cortex into > inflated surface only? > Run mri_vol2surf with --help and look for --projfrac-avg > > > thanks a lot, > > Reza > > > ------------------------------------------------------------------------ > *From:* Greve, Douglas N.,Ph.D. <dgr...@mgh.harvard.edu> > *Sent:* Tuesday, July 16, 2019 6:22:56 PM > *To:* Reza Rahmanzadeh; freesurfer@nmr.mgh.harvard.edu > *Subject:* Re: need for help > The command should be something like > tksurfer mysubject lh inflated -overlay output_of_vol2surf.mgz > Also, tksurfer is also obsolete (but should work).
