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 JSON ized representation and vice versa. JSON stands for JavaScript Object Notation, an open-standard format that uses human-readable text to transmit data objects consisting of attribute-value pairs.

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.

python3 -m pip install mwtab --upgrade

Upgrade on Windows

py -3 -m pip install mwtab --upgrade

Quickstart

>>> import mwtab
>>>
>>> # Here we use ANALYSIS_ID of file to fetch data from URL
>>> for mwfile in mwtab.read_files("1", "2"):
...      print("STUDY_ID:", mwfile.study_id)
...      print("ANALYSIS_ID:", mwfile.analysis_id)
...      print("SOURCE:", mwfile.source)
...      print("Blocks:", list(mwfile.keys()))
