Hi Doug,
I had some additional questions regarding multiple comparisons in
Freesurfer.
1) Do you correct the left and right hemispheres separately or combine both
together for muliple comparison correction?
2) Say you are testing multiple contrasts in your model: A > B, A< B etc.
Do you correct

Hi Doug,
Thank you very much for your update regarding this issue.

2)As for the cortical thickness I originally used 15mm in the analysis so
based on your email I think using 5-10mm may be more prudent
I have been doing simulations similar to #1 (Eklund) using
surface-based analysis on both thickness and fMRI. I'll prepare a report
of the results, but the early indications are that the same effect is in
play, though it does not look like the effects are as bad as in Eklund.
For thickness ana
Hello Freesurfer Experts,
Recently there were two article published regarding clusterwise
simulations for volumetric fmri analyses and potential errors for
underestimating clusterwise extent thresholds.
