Influenza Virus Sequence Database

Protein or nucleotide sequences can be retrieved from the database using GenBank accession numbers or search terms.

Multiple queries can be built by clicking the "Add Query" button every time a new query is made, and queries in any combination from the Query Builder can be selected to get sequences in the database. Sequences can be downloaded, and it is possible to analyze them using the multiple sequence alignment or tree building tool integrated to the database.
