⚠️There's a newer version (2.2) of this package.Take me there.

enviPat (version 1.7)

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.
