Hello,
I am trying to create ROI volumes from the hippocampal subfields I get from
mri_vol2vol --mov
/Volumes/DANIEL/dti_freesurf/dtrecon/${cond}.${subj}/lowb.nii.gz --targ
/Volumes/DANIEL/dti_freesurf/diffusion_recons/${subj}.${cond}/mri/lh.hippoAmygLabels-T1.long.v21.HBT.FSvoxelSpace.mgz
--inv --interp nearest --o
/Volumes/DANIEL/dti_freesurf/dtrecon/${cond}.${subj}/lhipp2diff.nii.gz
--reg /Volumes/DANIEL/dti_freesurf/dtrecon/${cond}.${subj}/register.dat
--no-save-reg
so that I can merge specific hippocampal subfields I want together into a
single ROI (like --id 231 and --id 232). However, when looking through the
freesurfer options like mri_vol2vol there isn't an option to index to
specific segments of the
lh.hippoAmygLabels-T1.long.v21.HBT.FSvoxelSpace.mgz volume
I have converted into dti space.
My plan is to combine the head and body segments and extract average
diffusion information from the combined mask.
Anything that can help get me in the right direction would be greatly
appreciated!
