If you are asking whether you can mix versions of FS, the answer is no. You should analyze all your data using a single version.

Hello,

I’ve got a question concerning qdec running with freesurfer. I just downloaded the latest version of freesurfer.

Before to run qdec, I read than I have to run "recon-all -s ID -all" (about 7 hours) and then recon-all -s ID -qcache (about 5'). So I tried it with one subject and everything is fine. Indeed, I got the files like *.fwhm5.fsaverage.mgh, *.fwhm10.fsaverage.mgh,  *.fwhm20.fsaverage.mgh, etc... in the surf folder absolutely necessary for qdec.

My question is very simple : I have already treated all my subjects (n = 45) two years ago. Today, I would like to use qdec. Do I need to restart _for each subject_ all my preprocessing with recon-all -s ID -allfollowed by recon-all -s ID -qcache ? or Is there a routine faster to get the smoothed surfaces for each subject ?

Many thank for ​any advice.

​Best wishes and happy new year.

Giovanni​
