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?
Thanks,
Clark
