Antonio, If you have built your own average subject, then to use in qdec, you will have to do the following:
1) run 'recon-all -s <subj> -qcache -target myaveragesubj' where 'myaveragesubj is the name you gave to your average subject. by default, the -qcache command resamples the subject data onto the fsaverage surface, which is what qdec uses, so the extra -target option has it use a different averague subject 2) in qdec, change the 'Common-space subject' box, in the Subjects tab, to the name of your average subject. Also, make sure that your average subject is in the same SUBJECTS_DIR as your other subjects. This can be set in the environment, or in the SUBJECTS_DIR text box in qdec.
