For qdec, there is a tutorial you can follow here:
https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis
You will have to create your own qdec.table.dat file containing the subjects in your group, and any information you want to regress against (such as age, gender, diagnosis). Discrete factors need the .levels files, which you must create.

hi, I have a problem. I analysis my data using qdec. But, after runing the command (recon-all -s subject1 -qcache) I can't find the qdec.table.dat and the discrete factor files.
The following commands that I type to run. First, I set SUBJECTS_DIR to a directory. setenv SUBJECTS_DIR $SUBJECTS_DIR/group_analysis cd $SUBJECTS_DIR Then, I run the pre-smoothed fsaverage surfaces recon-all -s subjects1 -qcache
Could you tell me what's wrong?
