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.

<dl><dt>xifti</dt>
<dd>The <code>"xifti"</code></dd>

<dd>The new label value for <code>NA</code> values. If <code>NULL</code>
(default), use -1 if all existing label values are non-negative, otherwise
use one less than the minimum existing label value.</dd>

<dd>The new label color for <code>NA</code> values, as a hex code with
alpha. Default: <code>"#FFFFFFFF"</code>.</dd>
<dt>idx</dt>
<dd>Numeric vector indicating the <code>"xifti"</code> columns to add
<code>NA</code> labels for. Default: <code>NULL</code> (add to all columns).</dd></dl>
