Parser for mwtab files from the Metabolomics Workbench
Project description
The mwtab package is a Python library that facilitates reading and writing files in mwTab format used by the Metabolomics Workbench for archival of Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) experimental data.
The mwtab package provides facilities to convert mwTab formatted files into their equivalent JSONized (JavaScript Object Notation, an open-standard format that uses human-readable text to transmit data objects consisting of attribute-value pairs) representation and vice versa.
The mwtab package can be used in several ways:
As a library for accessing and manipulating data stored in mwTab format files.
As a command-line tool to convert between mwTab format and its equivalent JSON representation.
