Jamie,

The Qdec app a basically a gui-wrapper for mri_glmfit, which takes as input a file in the 'fsgd' format, so fsgd formatted files are still relevant (and, in some cases, the only way to conduct a particular analysis). Qdec will generate an fsgd file for its analysis.

The 'fsaverage' subject is included in the freesurfer/subjects directory. You can just copy it to your subjects dir, or make a symbolic link.

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.
