Dear AFNI experts,

I tried running 3dFDR for the contrast t-value brik, and none of the values survived. I started to wonder whether I did something wrong and I used '-list' to check the printed p and q values. However, there was nothing output but only the following messages were written into the file:

Reading input dataset: biVau_0-100ms,20-40Hz+tlrc.BRIK
ibrick = 1 statcode = fitt
Processing sub-brick #1

Here is the command I used:
>>3dFDR -input biVau_0-100ms,20-40Hz+tlrc -cind -list > q_test -output test

So I tried the old 3dFDR with '-old', and with the old one I can print out the list of p and q values. Can someone tell me why the list can only be printed out with the old method?

Also, is it necessary to mask out non-brain areas before doing 3dFDR? will the results make much difference?

Thanks in advance for some answers!

Yuhan
