  "Description": "Utilizing model-based clustering (unsupervised) for\nfunctional magnetic resonance imaging (fMRI) data. The\ndeveloped methods (Chen and Maitra (2023)\n<doi:10.1002/hbm.26425>) include 2D and 3D clustering analyses\n(for p-values with voxel locations) and segmentation analyses\n(for p-values alone) for fMRI data where p-values indicate\nsignificant level of activation responding to stimulate of\ninteresting. The analyses are mainly identifying active\nvoxel/signal associated with normal brain behaviors. Analysis\npipelines (R scripts) utilizing this package (see examples in\n'inst/workflow/') is also implemented with high performance\ntechniques.",
