If you want to transfer a segmentation, then it is better to use mri_label2vol with the --seg option. Run it with --help to get examples. Probably even better is to transfer your functional to anatomical space (mri_vol2vol) so that it is in registration with the anatomical; transferring it to anat space handles partial voluming better.

Hi,
I just finished reconall and now I'd like to convert the aseg.mgz to native functional space. My first thought was to simply convert the aseg.mgz to native functional space with mri_vol2vol: mri_vol2vol --mov sub001/mri/aseg.mgz --targ example_func.nii.gz --o aseg-in-rawavg.nii --regheader Is this a valid procedure to convert the aseg to functional space? I think the recommended way is to register the example_func to anatomical first: bbregister --mov example_func.nii.gz --s sub001 --reg reg.dat and then use mri_vol2vol with the --inv flag mri_vol2vol --mov sub001/mri/aseg.mgz --targ example_func.nii.gz --o aseg-in-rawavg.nii --regheader --inv But I'm not sure... Could someone confirm which of the above (or maybe none of them) is correct?
Best regards, Sam
