In Weng's Benchmark 4 (Huang et al. 2010), the 85 cases which have available evolutionary
information (Andreani et al., 2013) were used for benchmarking InterEvDock server. Here, the
unbound target and ligand structures have ChainID 'A' and 'B', respectively. The reference PDB file
is the complex structure with ChainID 'A' for the receptor and 'B' for the ligand.
