make_mesh

Make INLA triangular mesh from faces and vertices

Performs a spatial Bayesian general linear model (GLM) for task
functional magnetic resonance imaging (fMRI) data on the cortical surface.
Additional models include group analysis and inference to detect thresholded
areas of activation. Includes direct support for the 'CIFTI' neuroimaging
file format. For more information see A. F. Mejia, Y. R. Yue, D. Bolin, F.

make_mesh function

<dl><dt>vertices</dt>
<dd>A \(V \times 3\) matrix, where each row contains the Euclidean
coordinates at which a given vertex in the mesh is located. \(V\) is the
number of vertices in the mesh</dd>
<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>use_INLA</dt>
<dd>(logical) Use the INLA package to make the mesh? Default:
<code>TRUE</code>. Otherwise, mesh construction is based on an internal function,
<code>galerkin_db</code>.</dd></dl>

Arguments

This function requires the <code>INLA</code> package, which is not a CRAN package.
See <a href="https://www.r-inla.org/download-install">https://www.r-inla.org/download-install</a> for easy installation instructions.
