    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).

 
Select: 
Add/remove reference sequences as Accession|subtype:   Enter local reference sequences as FASTA:
 
Enter your query sequence as Accession/GI or FASTA  
     
Enter window size:  Select background color: 
Enter increment step:  Similarity threshold (%):
