Hey Naveen, I know that there are some epitopes that can only be recognized if there's a weird domain swap that happens, causing antibodies to be "four-pronged" instead of "two pronged". I think it's a proline substitution in the conserved neck region. Did you screen out those epitopes from your ML?

Also good luck! I'm chipping in now. I'm relaunching my own crowd-funded nonprofit research in the biomedical space (and will be partnering with crowdhoster/crowdtilt)... I'm magnifying your message. When the dust settles a little bit I'd love to be in touch with you guys.
