About ArrayExpress

What is ArrayExpress?

ArrayExpress is one of the repositories recommended by major scientific journals to archive functional genomics data from microarray and sequencing platforms to support reproducible research. To serve this mission we facilitate submissions in compliance with Minimum Information About A Microarray Experiment (MIAME) and Minimum Information About a Sequencing Experiment (MINSEQE) guidelines. Experiments are submitted directly to ArrayExpress or are imported from the NCBI Gene Expression Omnibus database. For high-throughput sequencing based experiments the raw data is brokered to the European Nucleotide Archive, while the experiment descriptions and processed data are archived in ArrayExpress.

The team behind ArrayExpress

The ArrayExpress team is part of the Functional Genomics group at EMBL-EBI, led by Alvis Brazma. The team consists of about fifteen bioinformaticians, ontologists, software engineers and web developers, split between the production team led by Irene Papatheodorou and development team led by Ugis Sarkans. The production team manages, curates and models all incoming data to ArrayExpress, while the development team looks after all the back-end database infrastructure and the public-facing website.
