Cortical Parcellation

The FreeSurfer utilities mris_ca_train and mris_ca_label together implement a technique for automatically assigning a neuroanatomical label to each location on a cortical surface model based on probabilistic information estimated from a manually labeled training set (made using FreeSurfer). This procedure incorporates both geometric information derived from the cortical model, and neuroanatomical convention, as found in the training set. The result is a complete labeling of cortical sulci and gyri.

Background

Utilities

  • [wiki:mris_5fca_5ftrain mris_ca_train] - creates the reference atlas

  • [wiki:mris_5fca_5flabel mris_ca_label] - parcellates a cortical surface based on the reference atlas

Atlas

discuss default atlas, discuss creation of own atlas

FAQ

  • What if I have a labeled volume? How can I use it to create a labeled surface?
