Overlapping clusterings. This figure shows the overlapping clustering on the PPINs in Fig. 2 obtained by AligNet. We can see here the 8 clusters in the network in Fig. 2 on the left, and the 9 clusters in the network in Fig. 2 on the right. The center of every cluster is highlighted in blue. Since we have considered two small pieces of a PPIN, we obtain here that, the first cluster on the left is the entire piece of network. In the right, we obtain also the entire piece of network in the second cluster on the right. Notice that we obtain the whole piece of the network when we consider the cluster of a node that is in the center of the network
