vert_adjacency

Make adjacency matrix between two sets of vertices on the same mesh.

CIFTI files contain brain imaging data in "grayordinates," which
represent the gray matter as cortical surface vertices (left and right) and
subcortical voxels (cerebellum, basal ganglia, and other deep gray matter).
'ciftiTools' provides a unified environment for reading, writing,
visualizing and manipulating CIFTI-format data. It supports the "dscalar,"
"dlabel," and "dtseries" intents. Grayordinate data is read in as a "xifti"
object, which is structured for convenient access to the data and metadata,
and includes support for surface geometry files to enable
spatially-dependent functionality such as static or interactive
visualizations and smoothing.

vert_adjacency function

<dl><dt>faces</dt>
<dd>An \(F \times 3\) matrix, where each row contains the vertex
indices for a given triangular face in the mesh. \(F\) is the number of
faces in the mesh.</dd>
<dt>v1, v2</dt>
<dd>The first and second set of vertices. These are logical vectors
the same length as <code>vertices</code> indicating the vertices in each set.
If <code>v2</code> is <code>NULL</code> (default), set <code>v2</code> to <code>v1</code>. Can
alternatively be a vector if integers corresponding to vertex indices.</dd></dl>
