enviPat (version 2.1)

Isotope Pattern, Profile and Centroid Calculation for Mass Spectrometry

Description

Fast and very memory-efficient calculation of isotope patterns, subsequent convolution to theoretical envelopes (profiles) plus valley detection and centroidization or intensoid calculation. Batch processing, resolution interpolation, wrapper, adduct calculations and molecular formula parsing.
