| Automated parcellation of cerebral cortex into specific neuroanatomical regions of interest. Recommended usage with surface-based cortical labels made using FreeSurfer. |
= 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. |

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.
