External Email - Use Caution

Hello,

I have run through dt_recon and want to use anatomically based segmentations (aseg) to create ROIs for the diffusion-weighted data using mri_vol2vol.

I ran

mri_vol2vol --mov $subj_dir/dtrecon/${subj}.${cond}./lowb.nii.gz --targ $subj_dir/diffusion_recons/${subj}.${cond}/mri/aparc+aseg.mgz --inv --interp nearest --o $subj_dir/dtrecon/${subj}.${cond}./aparc+aseg2diff.nii.gz --reg $subj_dir/dtrecon/${subj}.${cond}./register.dat --no-save-reg

Which worked.

I now want to quality check and make sure the ROIs I make from the aseg2diff segmentation is accurately aligned in diffusion space (such as making sure the hippocampal ROIs for aseg are actually going to overlay the hippocampal region of the diffusion data). My question is what is the best way to quality check for quality registration between the diffusion and anatomical data?
