Important Update

As of February 2025, NCBI's Viral Genotyping Tool will no longer be available.
For up-to-date virus sequence data and analysis tools, please visit NCBI Virus: https://www.ncbi.nlm.nih.gov/labs/virus.
    This tool helps identify the genotype of a viral sequence. A window is slid along the query sequence and each window is compared by BLAST to each of the reference sequences for a particular virus. This approach is especially useful for the analysis of recombinant sequences.   (Try an example).
