froi is a suite of programs for the analysis of functional magnetic resonance imaging (fMRI) data using a region-of-interest (ROI) approach. Users can perform all necessary functions with froi, from creating and modifying ROIs, to using ROIs as a way to constrain analyses, to combining ROIs in a number of different ways.
froi is used in nearly all research of the Kanwisher Lab, with the results of analyses performed with froi published in journals such as The Journal of Neuroscience. froi is also in use in other research laboratories.
froi is currently written in a combination of perl, shell scripts, and matlab, and was planned to be re-written in python and C.
