This is to predict the antigenic relationship (either antigenic variant or antigenic similar) between viruses based on the HA1 protein sequences
Step 1: Please select the HA subtype
Step 2: Please input the HA1 protein sequences of your virus in fasta format(example of H9 subtype)
Paste your sequences or load from local file
Step3:Please input the HA1 protein sequences of your reference strains in fasta format
Please paste your sequences directly, or load them from local file(example of H9 subtype)
Step4: select the models(help)
