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.

Example
mris_sample_parc -ct FooColorLUT.txt subject01 lh subj01_parc_masks.mgz lh.parcmask.annot
This samples the volumetric parcellation subj01_parc_masks.mgz as an annotation lh.parcmask.annot for the subject subject01's left hemisphere. The output annotation is embedded with the color table information in FooColorLUT.txt file, and is usually saved in $SUBJECTS_DIR/$SUBJECT/label/ directory.
