1. Select species and gene to search (Option A) OR select a sequence file to upload and search (Option B).

   Option A. Select species and gene.

   Use the popup list to select to search by gene description, gene name (i.e. symbol), or Entrez Gene ID
   and then enter search criterion in the text box. You can use an asterisk (*) as a wildcard if you wish
   to perform a non-exact search on gene name. Gene description searches are always non-exact
   and the criterion is treated as a phrase.

   Option B. Alternatively, upload a sequence file to be searched. The sequence file may have a definition line (e.g. FASTA).
   The file must be plain text, though it may be zipped if you like. The search is limited to 3 M bases.

2. Set parameters for your search.
