Paul,
You don't need to reprocess the data with v4 to use qdec. It is ok to run the -qcache option in v4 on v3-processed data, so your approach is fine.

Hi all,
Will the QDEC program and the associated preprocessing steps (recon-all / -qcache) run correctly with data from Freesurfer version 3.0.5, or do all data sets first need to be reprocessed with version 4.0.2? I downloaded stable version 4.0.2, ran recon-all /- qcache on my previous data, and wanted to know if this approach was correct.
Thanks much, Paul
