Description: Converts NIfTI format T1/FL neuroimages into structured,
    high-dimensional 2D data frames with a focus on region of interest
    (ROI) based processing. The package incorporates the partition
    algorithm, which offers a flexible framework for agglomerative
    partitioning based on the Direct-Measure-Reduce approach. This
    method ensures that each reduced variable maintains a user-specified
    minimum level of information while remaining interpretable, as each
    maps uniquely to one variable in the reduced dataset. The
    partition framework is described in Millstein et al. (2020)
    <doi:10.1093/bioinformatics/btz661>. The package allows
    customization in variable selection, measurement of information
    loss, and data reduction methods for neuroimaging analysis and
    machine learning workflows.
