Alleles Similarity and identified motifs. (A) Pairwise correlations between alleles, based on a vector of frequencies of the 20 amino acids at every peptide position(left), and the Simpson coefficient (right). (B) 2D-visualization of sub-motifs identified across alleles (left), colored according to HLA locus and scaled in size according to the number of underlying peptides making up the sub-cluster. (C) Number of alleles sharing a sub-motif colored according to HLA locus.
