Hello,
I'm attempting to convert labels from one subject's cortical surface to locations or nodes on another's cortical surface via spherical registration. My thought was to use mri_label2label, e.g.
mri_label2label --srcsubject Bob --srclabel Bob/label/lh.cortex.label --trgsubject bert --trglabel Bob/label/bobToBert.lh.cortex.label --regmethod surface --hemi lh
My understanding is that this should translate the labels for the nodes on Bob's lh surface to labels/nodes/locations (I'm not really sure which) on bert's lh surface. However, each label file seems to end up with a different number of labels.
Bob/label/lh.cortex.label: 146415 Bob/label/bobToBert.lh.cortex.label: 122917 bert/label/lh.cortex.label: 122108 bert/label/bertToBob.lh.cortex.label: 145629
Can someone explain more precisely what mri_label2label does and what output it produces?
Thanks.
