3dFDR for resting state FC map

Hi all!

I’m doing resting state fMRI analysis and ran 3dTcorr on a group of patients. I have the resulting FC map where you can change the pearson correlation threshold with the slider in the AFNI GUI. Is there a way to create an FC map that has been FDR-corrected? I was looking at the 3dFDR command, but the output creates a z-scored map that changes the p-value in GUI, not the q-value.

Any help would be appreciated!
