Create one parcel, i.e. a named set of surface vertices (per structure) and volume voxels. The name is the only label a parcellated file has: the position in the list of parcels is the parcel index, and the reader returns the names.
Arguments
- name
character string, the parcel name.
- vertices
named list or
NULL, the 0-based vertex indices per brain structure, e.g.list(CORTEX_LEFT = c(0, 1, 2), CORTEX_RIGHT = c(4, 5)). Structures without vertices are left out.- voxel_indices_ijk
n x 3 integer matrix or
NULL, the 0-based voxel indices of the parcel, one voxel per row.
Value
a named list, one parcel, to be passed to cifti.axis.parcels.
