Bayesian Hierarchical Multi-Subject Multiscale Analysis of Functional MRI (fMRI) Data R package BHMSMAfMRI version 2.3 Package BHMSMAfMRI performs Bayesian hierarchical multi-subject multiscale analysis of fMRI data as described in Sanyal & Ferreira (2012) <DOI:10.1016/j.neuroimage.2012.08.041>, or other multiscale data, using wavelet-based prior that borrows strength across subjects and provides posterior smoothed images of the effect sizes and samples from the posterior distribution.
