Figure 2From: Predicting direct protein interactions from affinity purification mass spectrometry dataExample of a direct interaction network and its connectivity matrix. An example of a direct interaction network G Direct (left) with its connectivity matrix P G D i r e c t (right) calculated with p ^ = 1 2 . Assuming each edge of G Direct survives with probability p ^ , the probability of connectivity between each pair of protein can be estimated via sampling of the probabilistic network.Back to article page
