BayesfMRI

The BayesfMRI R package includes the main function BayesGLM, which implements a spatial Bayesian GLM for task fMRI. It also contains a wrapper function BayesGLM_cifti, for CIFTI cortical surface fMRI data.

Installation

You can install BayesfMRI from CRAN with:

install.packages("BayesfMRI")

Vignette

See this link to view the tutorial vignette.

Important Note on Dependencies:

BayesfMRI depends on the ciftiTools package, which requires an installation of Connectome Workbench. It can be installed from the HCP website.

The INLA package is required, which, due to a CRAN policy, will not be installed automatically. You can obtain it by running install.packages("INLA",repos=c(getOption("repos"),INLA="https://inla.r-inla-download.org/R/stable"), dep=FALSE). For more information, see the INLA website. Note: INLA must be installed before installing BayesfMRI.

On Mac platforms, an installation of Xcode is necessary to build the C++ code included in BayesfMRI.
