Hello,<br><br>I&#39;m attempting to convert labels from one subject&#39;s cortical surface to locations or nodes on another&#39;s cortical surface via spherical registration.  My thought was to use mri_label2label, e.g.<br>
<br>mri_label2label --srcsubject Bob --srclabel Bob/label/lh.cortex.label  --trgsubject bert --trglabel Bob/label/bobToBert.lh.cortex.label --regmethod surface --hemi lh<br><br>My understanding is that this should translate the labels for the nodes on Bob&#39;s lh surface to labels/nodes/locations (I&#39;m not really sure which) on bert&#39;s lh surface.  However, each label file seems to end up with a different number of labels.<br>
<br>Bob/label/lh.cortex.label: 146415<br>Bob/label/bobToBert.lh.cortex.label: 122917<br>bert/label/lh.cortex.label: 122108 <br>bert/label/bertToBob.lh.cortex.label: 145629 <br><br>Can someone explain more precisely what mri_label2label does and what output it produces?<br>
<br>Thanks.<br><br>--<br>Stephen Tyree<br>Neuroimaging Computer Scientist<br>Laureate Institute for Brain Research<br>Tulsa, OK, USA<br>
