Reference validator for mzTab 2.0-M

mzTab 2.0 for metabolomics is a data exchange format for mass-spectrometry-based experimental data from the "omics" and neighboring sciences, focusing on small molecules like metabolites and lipids.

  • It is hierarchically organized, from metadata to summary information to mass spectrometry (MS) features and evidence,
  • captures quantitative and qualitative information about reported molecules for individual MS runs and aggregated across study variables,
  • follows minimum recommended reporting guidelines for omics experiments,
  • provides structural and logical validation, and
  • semantic validation based on controlled vocabulary (CV) terms.

This application provides a web-based validator for mzTab 2.0-M and the prior mzTab version 1.0 (mainly for proteomics) below, and a REST API for programmatic validation against mzTab 2.0-M.

Validation

Upload your mzTab file for validation:

Select a local mzTab file to upload and validate. Size limit is 64MB.
The 'Info' level includes 'Warn' and 'Error' level messages, the 'Warn' level includes 'Error' level messages.
The maximum number of parsing and logical validation errors that should be reported, minimum of 1.
The mzTab specification version to use for validation. mzTab 1.0 files will not pass the 2.0 validation and vice-versa.
If checked, use the provided or default cvMapping file to validate cv terms in the mzTab file. This will only work for mzTab 2.0+ files.
