Saddle plots showing contact interactions between A and B compartments in each species, organized by eigenvector ranking. To obtain the distance-normalized matrix, the ratio of observed-over expected interactions is calculated, followed by eigenvector decomposition. The eigenvectors are oriented and sorted from the lowest (B compartment) to the highest (A compartment) values. The bins of the interaction matrix then reordered according to the rank of the eigenvector. The observed (O) and expected (E) values are averaged to create a saddle plot. The top 20% of the interaction values were used to calculate the compartment strength values shown on the saddle plots.
