%description
A collection of data structures and methods for handling volumetric brain
imaging data, with a focus on functional magnetic resonance imaging
(fMRI). Provides efficient representations for three-dimensional and
four-dimensional neuroimaging data through sparse and dense array
implementations, memory-mapped file access for large datasets, and spatial
transformation capabilities. Implements methods for image resampling,
spatial filtering, region of interest analysis, and connected component
labeling. General introduction to fMRI analysis can be found in Poldrack
et al. (2024, "Handbook of functional MRI data analysis",
<ISBN:9781108795760>).
