Hi, I have a MT and T1W volume (processed through recon-all). I would like to extract all MT values that lie in the middle surface of the cortex, and run that through mri_segstats so I get average MT values for each cortical region in the DK-atlas.
My workflow is as follows: 1. mri_vol2suf --mov <MT_vol> --hemi lh --projfrac 0.5 -- regheader <id> --reg <MT_reg_to_T1W.dat> --o <vol2surf.output.mgh> --interp nearest 2. mri_surf2vol --surfval <vol2surf.output.mgh> --hemi lh --fillribbon --identity <id> --template <T1W> --o <surf2vol.output.mgh. 3. mri_segstats --seg <aparc+aseg for subid.mgz> --i <surf2vol.output.mgh> --ctab --id <list of regions> --o <output.stats> Is this the correct way of going about it? In essence I extract all the values of MT found in the middle of the cortex (#1), then I fill the cortex ribbon with these values in the subject's T1W vol (#2), and then run mri_segstats on that output so both aparc+aseg and the output from #2 are in the same space. Is there any other (more efficient) method to do this? Thank you, Yash RRI, Baycrest Health Sciences University of Toronto
