10 September 2015 - ArrayExpress submission now supports "double-blind" peer review

"Double-blind" review happens when the manuscript authors and reviewers remain anonymous to one another. It is expected to reduce potential bias during the review process, and some journals have started supporting it. ArrayExpress submission tool "Annotare" now supports double-blind review by allowing submitters to enable an anonymity feature, which ensures reviewers only have access to redacted versions of the experiments they're reviewing, with sensitive fields such as "Contact" removed from the meta-data. Please refer to this guide on submitter anonymity for further details.
