  1. aStatistical analysis was done on 193 out of 194 dimers. One dimer, with PDB-ID 2AJQ, is highly symmetric with S(C2) = 0.0001 for the Hungarian algorithm and 0.0004 for the sequence-ordered permutation, led to an error of 300%. It was therefore considered as an outlier and excluded from this calculation
