[Freesurfer] Peak coordinates & Paired t-test with QDEC

Dear Freesurfer experts:

I have two questions:

1) How can I obtain the *peak coordinates* and *the size* of the *clusters*(with uncorrected threshold) visualized in *tksurfer*? (like the tables generated with glmfit-sim)

2) *Is it possible to run paired t-test in QDEC*? I have run Paired Analysis as suggested by Doug Greve at https://surfer.nmr.mgh.harvard.edu/fswiki/PairedAnalysis, and it worked perfectly. I wonder to know if there is an alternative way to run paired t-test using QDEC.

(I apologize if these questions were previously answered. I did some search in the list, but I couldn't find the exact answer to my questions..)

Any comment or help will be very welcome. Thanks in advance, Jaime
