Meta-analysis of pancreatic cancer data. In this example, our goal was to retrieve the sets of overlapping genes between user's data obtained by a proteomics platform with IPI identifiers and those reported in the studies stored in the Pancreatic Expression database. 1. Filter: one can restrict the query by clicking on the "Filters" node on the left and expanding the filter section "GENE RELATED ACCESSIONS:" using the "+" box. Next one can choose the "ID" list limit simply by clicking on the left checkbox and selecting the identifiers for the experimental results from the right drop-down menu. In this example, the "IPI ID(s)" is used but one can choose any other identifiers such as Uniprot, Affymetrix or Illumina etc. One can copy and paste the list of identifiers in the box or browse to read directly from a file. 2. Attributes: one can click on the "Attributes" node on the left and start choosing attributes from the "General Gene Features" page. One can expand the "PANCREATIC EXPRESSION:" section or other sections and check other attributes to add to the results. 3. Results: for saving the whole result set, one can choose the appropriate action(s) at the top of the page, select the format, for example Excel, and click the "Go" button to export the results.
