One hundred medoid submatrices obtained from partitioning around medoids (PAM) analysis of distance matrices of 100 sampled proteins. They reflect 100 representative local structural features. Various combination of these features can reconstruct the original distance matrices of all 100 proteins. The medoid submatrices are indexed arbitrarily (from 1 to 100).
