In most real-time fMRI paradigms, suitable regions of interest (ROIs) must be computed quickly after localization scans have been acquired and before the real-time paradigm can begin. We have developed software that can quickly generate ROIs by leveraging existing software packages. We demonstrate our software by computing ROIs: 1) Using a functional localizer 2) using a structural scan and reference data (either an atlas or a previous scan of the subject) and 3) Using a functional localizer constrained by structural data. We validate our software using a finger-tapping paradigm and flashing checkerboard paradigm.
