%description
Utilizing model-based clustering (unsupervised) for functional magnetic
resonance imaging (fMRI) data. The developed methods (Chen and Maitra
(2023) <doi:10.1002/hbm.26425>) include 2D and 3D clustering analyses (for
p-values with voxel locations) and segmentation analyses (for p-values
alone) for fMRI data where p-values indicate significant level of
activation responding to stimulate of interesting. The analyses are mainly
identifying active voxel/signal associated with normal brain behaviors.
Analysis pipelines (R scripts) utilizing this package (see examples in
'inst/workflow/') is also implemented with high performance techniques.
