Determine H5N1 HA Clade
1. Choose a method:
BLAST is used by default. MegaBLAST is presumably a bit faster.
      BLAST     MegaBLAST
2. Choose Cutoff Values (change default values as needed):
      Coverage(%):       Identity(%):  

      Word Size:    E-Value:  
3. Choose number of files to load (nucleotide sequences only):
Sequence must be in the FASTA format. You can either "cut and paste" or "Upload a file" to load sequences. The Sample Data page shows examples of sequences in FASTA format.
