Alvaro,
if you go through the results procedure once and then click on the button
"whole brain",
you will get a results table in the Graphics window.
There, in the lower left corner, you should see four values:
FWEp, FDRp, FWEc, FDRc
These are the t-values or cluster extent values
for obtaining maps thresholded at P <= 0.05 using the respective
correction method (FWEp = family-wise error, height FWEc = cluster extent;
FDRp/c for FDR-correction using height and extent)
Just enter these values when going through the results procedure again.
As to how to get p<0.1, I am not sure, you'd probably have to look that up
in the code,
not sure where though - maybe someone else can comment on that?
Hope this helps,
Claus

Subject: [SPM] FDR p-threshold in SPM8
Hi all,
I'm trying to use FDR correction in SPM8 as explained in
https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=SPM;pxeBbw;20090406192205%2B0
100
However, I don't have a clear understanding of the equivalence between the T
and p threshold values. I would be very grateful if somebody could point
which value should I enter after clicking 'none' if I want to use a p<0.05
FDR threshold. And for a p<0.1 ?
Thank you very much for your help and guidance!
Best wishes,
Álvaro
