Hi VM,
They can stay all in the same .csv file. The "fwep" files will have
p-values corrected across all columns of this input.
All the best,

Hi,
We extracted volume measures from 7 ROIs in 2 groups and compared
a) Mean of each ROI volume between group, and compared independently such
as
i) whether mean of ROI 1 in group 1 is equal to mean of ROI1 in group 2
ii)whether mean of ROI 2 in group 1 is equal to mean of ROI2 in group 2
and so
Thanks, Anderson. If there are several other measures such as volume,
thickness, FA, can I then put them in a single csv file and run the
command or I have to create 3 csv files, one each for volume, thickness,and
FA and also invoke -corrmod?
Thanks

Hi Doug,

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.
