The MAGE-TAB specification
The MicroArray Gene Expression Tabular (MAGE-TAB) format has been developed and adopted by the functional genomics community as a means of representing and communicating data about a functional genomics experiment in a structured and standardised way (Rayner et al., 2006). It was designed for data collection and annotation, as well as for data exchange between tools and databases, including submission tools to public repositories such as ArrayExpress. The full specification outlines the format.
How to create MAGE-TAB files manually
Note: This is not required anymore for standard ArrayExpress experiment submissions. Annotare automatically converts metadata into MAGE-TAB format upon submission.
