Figure 3From: A geometric and algebraic view of MHC-peptide complexes and their binding propertiesRELATION L, defined on function D so that two elements d1(h1, p1) and d2(h2, p2) are related if h1 and h2 are sequence properties characteristic of the same MHC allele. Collection Q is the set of elements in D related to each other according to L; since L is not an equivalence relation, Q is not a partition.Back to article page
