BLAST Demo 2

This page uses the Java SStructView applet and JavaScript to search for similar sequences using the NCBI's BLAST search engine. Select a range of bases (click on a base and drag to another base), then hit the "Copy To Form" button. The selected sequence will be copied into the Sequence field. Change any other search parameters you wish, then click on "Submit".

Note: this page is based on the original BLAST search form, found here.

The applet is linked to BLAST using JavaScript. The "Copy to Form" button's script is: 
<INPUT	TYPE="button"
		VALUE="Copy To Form"
		onClick="this.form.SEQUENCE.value = document.SSApplet.getVariable('SUBSEQ-VAL')">
The HTML code to show the applet is: 
<APPLET CODE="SStructView.class" ARCHIVE="SStructView.zip" NAME="SSApplet" width=400 height=300>
<PARAM name="structure-data-URL" value="http://smi-web.stanford.edu/projects/helix/sstructview/data/e.coli16s.coord">
