Hi Clark
you shouldn't need either. Load your overlays then click the button to compute the FDR threshold in the tksurfer configure overlay interface.

Ok, maybe I'm making this question too intricate. Here's the short version: How can I FDR correct painted surface significance maps when I have no talraich .xfm file and no cortical segmentation?
Thanks again, Clark
Hi Freesurfers,
I have another monkey-specific question. I'd like to output FDR-corrected signficance surface maps for my monkey data, or at least FDR-threshold the maps. It seems like mri_surfcluster might be one way to go about this however: 1) I don't have any .xfm files for my monkeys, as I'm working in native space, and 2) Without segmentation, I don't have a good mask to use for the cortex only.
My first attempts at work-arounds would be: 1)Try to create an identity .xfm file 2)Use the cortical ribbons from mris_volmask as a cortex mask
Should these work? If so, how should I make an identity .xfm file? If not, is there another way to FDR correct my surface data?
