Influenza Virus Alignment

Important Update

In Fall 2024, NCBI plans to redirect the Influenza Virus Resource to NCBI Virus. We are working to replicate the highly-used features from this resource prior to the redirection. Learn more.

This tool is used to make a multiple sequence alignment with protein, coding region or nucleotide sequences obtain from the database with the option of additional sequences provided by users.

The maximum number of sequences that can be included in an alignment is 1000.
