Decon2 - a manual deconvolution spreadsheet.

An excel-based deconvolution routine. It will calculate nominal molecular weights from an ion series, or - starting with a single ion - will calculate other expected members of a series. Works with either positive or negative ions.

It's designed for pulling information out of noisy data, so it's not as fast or as slick as most of the commercial deconvolution routines. It's especially nice for people who are just beginning mass spec on multiply-charged species, since it's not a black box treatment of charge envelopes. If you're good at excel, you can probably convert it into an automatically-iterated version, but I like the manual version because it's instructive and intuitive.
