ready Metabolomics Workbench Tabular File Format

Abbreviation: mwTab

General Information
mwTab is a format developed by the Metabolomics Workbench to facilitate programmatic processing of data suitable for submission to the Workbench. It provides a structure for both metadata and experimentally measured data. The mwTab format consists of sequentially ordered blocks (sections) of text data. Some of the blocks consist of data represented by ‘single key to single value’ relationships that store single pieces of information. Other blocks consist of multiple ‘tab’-separated values via ‘single key to multiple values’ or ‘multiple keys to multiple values’ relationships that store multiple pieces of information in an organized manner analogous to a relational table.
