Before revision:   When tested on a set of protein families from PFAM , we found the RLS algorithm to have superior performance compared to PSICOV, a state-of-the-art method for contact prediction  .
After revision:  When tested on a set of protein families from PFAM , we found the RLS algorithm to have superior performance compared to PSICOV, a state-of-the-art method for contact prediction , while at the same time being faster and conceptually simpler .
