UniDec: Universal Deconvolution of Mass and Ion Mobility Spectra

UniDec is a suite of computational tools built around a core Bayesian deconvolution algorithm. UniDec is fast, robust, and easily generalized to mass and ion mobility spectra. It scales nicely from very simple spectra to highly polydisperse ensembles.
