The European Bioinformatics Institute (EMBL-EBI) has developed a data submission wizard to find the right archive for each user’s data. The tool guides you through a few simple steps. In the first step, the user is asked to choose from different data types (DNA/RNA sequence, Expression data, Protein data, Structures, Systems, Chemical biology, Ontologies, Multi-omics or other cross-domain study). Depending on the choice, following steps involve providing input about whether data involve human research data that require controlled access, about data collection and analysis methodology (e.g. study or technology type), and further details about the data. After completing 2 to 4 steps, the tool will suggest a data repository which is appropriate for the user’s data.
