read_surf

make_surf

Coerce a file path to a surface GIFTI, a <code>"gifti"</code> object, a list with
entries "pointset" and "triangle", or a <code>"surf"</code> to a
<code>"surf"</code>.

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.

read_surf function

<dl><dt>surf</dt>
<dd>Either a file path to a surface GIFTI; a <code>"gifti"</code>
read by <code>readgii</code>; a list with entries "pointset" and
"triangle"; or, a <code>"surf"</code> object.</dd>
<dt>expected_hemisphere</dt>
<dd>The expected hemisphere (<code>"left"</code> or <code>"right"</code>)
of <code>surf</code>. If the hemisphere indicated in the GIFTI metadata is the
opposite, an error is raised. If <code>NULL</code> (default), use the GIFTI
hemisphere.</dd>
<dt>resamp_res</dt>
<dd>The resolution to resample the surfaces to. If <code>NULL</code>
(default), do not resample.</dd></dl>
