In order to make microarray results fully available to the research community in a form that allows independent evaluation, publication of microarray data to a public data repository is ever-increasingly a requirement for publishing to a scientific journal. Many online, public data repositories exist and some of the most commonly accepted repositories include Gene Expression Omnibus (GEO), ArrayExpress, and the Center for Information Biology Gene Expression Database (CIBEX). Some scientific journals define which online public data repository to use while others do not.
Once an online data repository has been selected, preparing microarray data for online publication can be divided into two major steps: 1) Collating, formatting, and reviewing all experimental annotation or "metadata" in compliance with standards defined by the Microarray Gene Expression Data Society (MGED) and 2) Preparing raw and processed data files for submission.
MGED standards, referred to as the "Minimum Information about a Microarray Experiment" or MIAME
The Gene Microarray Shared Resource (GMSR) is available to provide general tutorials regarding online publication of microarray data or on a fee-for-service basis to support investigators in a customized manner through the entire online publication process.
