Parallel partitions maps modules between clusterings. Horizontal bands represent partitions, and modules are separated by blank spaces. Semi-transparent bands connect the same items from different clusterings. Red traces highlight selected items across all partitions and show how modules split and merge. Here, the user has selected a group of 215 proteins that belong to the largest core in the ensemble of clusterings for A. thaliana PPI network. The Louvaine, Clauset, MCL, and MCODE.F clusterings assign all of the selected proteins to a single module. For other clusterings, most of the selected proteins are placed in a grab bag region of items that were not contained in any module (shown in gray).
