Hello everyone,
I’m encountering an error while performing FOD registration using the following mrregister command:
mrregister wmfod.mif -mask1 dwi_mask_upsampled.mif …/…/template/wmfod_template.mif -nl_warp subject2template_warp.mif template2subject_warp.mif
mrregister: SH image input pair wmfod.mif, …/…/template/wmfod_template.mif
mrregister: performing FOD registration

Thank you in advance for your help,
