HXMS: a standardized file format for HX/MS data.

ABSTRACT:

Motivation

Hydrogen-deuterium exchange/mass spectrometry (HX/MS) is a rapidly expanding technique used to investigate protein conformational ensembles. The growing popularity and utility of HX/MS has driven the development of diverse instrumentation and software, resulting in inconsistent, non-standardized data analysis and representation. Most HX/MS data formats also employ only centroid-level representations of the data rather than full isotopic mass spectra, reducing the information content of the data and limiting downstream quantitative analysis.

Results

Inspired by reliable protein structure and genomics data formats, we present HXMS, a unified, lightweight, scalable, and human-readable file format for HX/MS data. The HXMS format preserves the isotopic mass envelopes f
