HI AFNI Experts!

I have a quick question:

I have a statistical dataset ( output of 3dANOVA3 ) across subjects in TT-space containing F-statistics for the the main effects and interactions (3 BRIKS: #1, #3, #5). Contrasts of factor levels contain t-statistics (another 11 sub-BRIKS).

I want to calculate FDR for all sub-BRIKS. In the 3dFDR manual example 3 explains, how to use this program to convert t-statistics into FDR z-scores.
However, I wonder, if I have to do something different to the subbricks containing F-statistics. Example 2 mentions something like this in a little bit different context.
1) How should I calculate FDR z-scores in my context?
2) And how can I combine these two output file into one bucket, if two different commands are necessary.

Thanks,

Lukas
