Hi Freesurfers,
I have talairach coordinates of electrodes sitting on the brain. I am hoping to use the Desikan-Killiany parcellation scheme to determine which cortical region each electrode lies closest to in standard space. I am using read_annotation in matlab to read the lh.aparc.annot file and find the vertices associated with each label. I am wondering how to determine which label each electrode lies closest to? Is there a TAL or RAS to vertex function in matlab? Thanks.
Best, Corey
