[Freesurfer] after recon-all.

Hey Folks-

So I just finished autorecon-all on a few subjects and wanted to do some prelim analyses. On the tutorial pages, there is some talk of using QDEC or FSGD... I couldn't really find a good page contrasting the two... or is there not a difference? Is FSGD just a dated version?

And per the tutorial pages, I need to have pre-smoothed fsaverage surfaces using recon-all -s <subjid> -qcache. I keep getting an output of ERROR: cannot find fsaverage in /study/eemri/freesurfer, which is my subject dir. So I switched to doing mris_preproc for each subject. But I keep getting an ERROR: Cannot find fsaverage (output).

So what am I doing wrong? Which target should I specify?

Best, jamie.
