Name

mris_sample_parc - Samples a volumetric parcellation onto a surface. Manual labeling can be carried out directly on surface models using drawing tools in tksurfer, or volumetrically in tkmedit, then sampled onto the surfaces using mris_sample_parc. mris_ca_train is used to create an atlas from a set of annotated subjects. The information output by mris_ca_train is then used by mris_ca_label to automatically assign a neuroanatomical label to each location on a cortical surface model. Note that an "annotation" is synonymous with a "parcellation", and is used for backwards compatibility.
