You can do it in QDEC by going running QDEC, then loading the surface, curvature, and overlay files (they are in the output folder (default "Untitled")). Load the "sig.mgh" file for the overlay. This can also be done in tksurfer. doug

Dear Freesurfer experts,

I ran some surface-based group analysis using Qdec. I would like to re-open those analysis and threshold them using FDR, for example. I read through the Qdec tutorial and it points out how to do so for new analysis, however there is no mention on how to open previously ran analysis.

My questions are: 1. Is there a way to open previously ran group analysis in Qdec, or do I have to re-run it every time?; 2. What other program might allow me to open previously ran group analysis (and use multiple comparisons correction) if Qdec cannot do it: freeview, tksurfer?

Thank you.
