Non-antigens

The non-antigens were determined by BLAST protein sequences randomly selected from Viral Bioinformatics Resource Center against hundreds of antigens we manually curated from the literatures containing tested immunogenic protein data. 

A total of 48210 9-mer peptides were derived from 100 non-antigens by 9-mer sliding window with the step size of one amino acid. The intrinsic features were calculated for all the 9-mers from non-antigens, which can be downloaded from here .
