clustered_searchlight

This function generates a searchlight iterator that iterates over successive
spatial clusters in an image volume. It allows for the exploration of spatially
clustered regions within the provided mask by using either a pre-defined
clustered volume or performing k-means clustering to generate the clusters.

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>).
