The "raw" output of the fasta program (text) has been postprocessed by the website into a nice layout. fasta program is run on the server of EBI with the parameters you provided.We will choose the default FASTA program, and click Since we want to search nucleotide, we have to switch to the Nucleotide Databases' under 'Other types' in a box at the right side of the screen.Īfter that, we can select the database and our query sequence.

You can use, search and download the sequence.īy default the FASTA search page is set up for protein similarity search. Since we have a universal accession number we can use all major portals. Try yourself first, click 'Show' for tips.
Get the sequence with accession number M25165 in fasta, download it and save as M25165.fasta. (Note:running against the complete EMBL databank as compared to the bacteriophage section would take to much time for this exercise session - remember that fasta is rather slow). We will search with a fragment of the bacteriophage lambda genome containing the third right operator (OR3) and the right promoter (PR) to find similar sequences in the bacteriophage section of EMBL databank. Go to, then select the menu item "Tools"/"Similarity & Homology"/"FASTA". We will use the FastA server of the EMBL-EBI, which has a richer collection of databanks. FastA is older than the popular BLAST, it is slower, but sometimes finds things that BLAST does not find, especially for non-coding DNA (e.g. Pearson's FastA finds similar sequences in a database given a query sequence.
