Hello FS team,
If I want to calculate the average diffusion-weighted signal from a DWI image within WM regions using mri_segstats, would it be beneficial to use the --pv flag for "partial volume correction" , or would this only have an influence on the Volume calculation?
mri_segstats --seg ${whitemattermask} --i ${DTI_image} --sum ${ whitematter_stats} --excludeid 0
or
norm=${subject}/mri/norm.mgz mri_segstats --seg ${whitemattermask} --i ${DTI_image} --sum ${ whitematter_stats} --pv ${norm} --excludeid 0
Thanks, Julie
