Hello Freesurfers, I would like to use the muscle ROI in the LUT (number 123). Can anyone tell me which muscles (all cranial? cervical too?) are included? I tried making a subject-specific label using the following command: mri_cor2label --c /cluster/ablood/1/${experimental_directory}/${recons_directory}/${identifier}_recon/mri/aseg.mgz --id 123 --l /cluster/ablood/1/${experimental_directory}/${recons_directory}/${identifier}_recon/label/muscle_${identifier}.label
This yielded the error "Found 0 label voxels", presumably because aseg.mgz is skull-stripped. When I used orig.mgz instead of aseg.mgz in the command line above, the assigned label is a scattering of single voxels throughout the cortex and subcortical white matter. I am guessing that this is because orig.mgz is not registered to the same space as aseg.mgz - is this correct?
Any suggestions for how to use the muscle ROI would be much appreciated.
Thanks, Jeff
