Molecular formula assignment and mass recalibration with MFAssignR package

Abstract

This training covers the multi-element molecular formula (MF) assignment using the MFAssignR tool. It was originally developed by for the analysis of untargeted mass spectrometry data coming from complex environmental mixtures. The package contains several functions including noise assessment, isotope filtering, internal mass recalibration, and formula assignment.
