vertex.coords

Return coordinates for vertices, supporting entire brain via hemilist.

Provides high-level access to neuroimaging data from standard software packages like 'FreeSurfer' <http://freesurfer.net/> on the level of subjects and groups. Load morphometry data, surfaces and brain parcellations based on atlases. Mask data using labels, load data for specific atlas regions only, and visualize data and statistical results directly in 'R'.

vertex.coords function

<dl><dt>surface</dt>
<dd>an fs.surface instance, see <code>subject.surface</code> function. Can also be a hemilist of surfaces, in which case the vertices must be indices over both meshes (in range <code>1..(nv(lh)+nv(rh))</code>). If a hemilist, both entries must be surfaces (non-NULL).</dd>
<dt>vertices</dt>
<dd>vector of positive integers, the vertex indices. Values which are outside of the valid indices for the surface will be silently ignored, making it easier to work with the two hemispheres.</dd></dl>
