Examples of connectivity matrices. In a), the noiseless adjacency matrices have a modularity q-value of 0.5 and an L-value of 470. Gaussian noise of different variances is added to the uncorrupted adjacency matrix simulating noise. SNRdB values are decibels of the ratio between the adjacency matrix and the Gaussian noise. In b), L-values for modular matrices forming unconnected communities are calculated for noiseless (main plot) and noise added. In c), the plot is similar to b), but considering connected communities.
