MSPrep--summarization, normalization and diagnostics for processing of mass spectrometry-based metabolomic data.

ABSTRACT:

Motivation

Although R packages exist for the pre-processing of metabolomic data, they currently do not incorporate additional analysis steps of summarization, filtering and normalization of aligned data. We developed the MSPrep R package to complement other packages by providing these additional steps, implementing a selection of popular normalization algorithms and generating diagnostics to help guide investigators in their analyses.
