Searching and visualising data from ArrayExpress

The ArrayExpress interface (Figure 1, section 1) allows you to browse the entire database content or search the database using free text or keywords (Figure 1, section 2) . You can also search using experiment accession numbers (for example, E-MTAB-1199).

Results are displayed in a table view and can be filtered by organism, array, molecule assayed (for example, RNA or DNA) or technology used (for example, sequencing or array).

For each experiment, an expanded view (Figure 1, section 3) provides useful links to the information available for the selected experiment, such as data files and sample annotation, and all information can be easily downloaded (Figure 1, section 4).
