pct_sig

Convert data values to percent signal.

Supports fMRI (functional magnetic resonance imaging)
analysis tasks including reading in 'CIFTI', 'GIFTI' and
'NIFTI' data, temporal filtering, nuisance regression, and
aCompCor (anatomical Components Correction) (Muschelli et al.

pct_sig function

<dl><dt>X</dt>
<dd>a \(T\) by \(N\) numeric matrix. The columns will be normalized to
percent signal.</dd>
<dt>center</dt>
<dd>A function that computes the center of a numeric vector.
Default: <code>median</code>. Other common options include <code>mean</code> and
<code>mode</code>.</dd>
<dt>by</dt>
<dd>Should the center be measured individually for each <code>"column"</code>
(default), or should the center be the same across <code>"all"</code> columns?</dd></dl>
