Example Antigenic Mapping Data
Description
HI titers of Influenza antigens and antisera published in Smith et al., 2004 were used to find the antigenic relationships and coordinates of the antigens. It can be used for mapping. The data captures how different influenza virus strains (antigens) react with antisera from infected individuals.
Usage
