About esimsa

esimsa deconvolutes a peak list based only on mass differences between isotopic peaks. esimsa handles overlapping and resolved isotopic distributions but does not model the isotopic distributions themselves. Originally, esimsa was reposited here. Although this site is no longer maintained, it contains more information on esimsa.
