MSiReader — Free Open Source MS Imaging Software

MSiReader is a vendor-neutral Matlab application to view and perform data analysis of Mass Spectrometry Imaging (MSI) data. MSiReader is distributed as a standalone Windows application that does not require a Matlab license. Because binning is not performed on the imaging data until requested by the user, high resolving power data (small m/z increment) can be viewed and processed as long as the data set size does not exceed memory resources (RAM).
