Searching with blast
This search form allows you to enter a single DNA sequence for comparison to sequences held in the westDB database. The sequence you enter should be bare text, just composed of C's, A's, T's and G's plus ambiguity codes. Spaces, line breaks, numbers, and any other non-letter characters will be removed automatically (you will be warned if there were any). Your sequence does not have to fit in to the box, as scroll bars will appear if it is very large. There is a 32 Kb size limit (the size limit for web input) You should not have a fasta header line at the top of the sequence, as this may cause the search to fail. You can type a sequence in to the box by hand, but it's probably easier to use copy and paste (just click in the box then do EDIT PASTE from your browser menu, or simply use ctrl+v). When your sequence is in the box, click on the submit query button to launch a search. The results page will either tell you there were no matches, or display a summary table plus all alignments. More help is available on that page.

Hint
If you want to try this out, but you don't have a sequence handy, go to the string search page, type wheat in the query box, and click on a link to get a sequence which you can copy and paste in to this form.
