Abstract: Non-bonded interaction forces play crucial roles in molecular recognition and binding in biological systems.However, it is difficult for traditional methods to automatically calculate and batch the non-bonded energy at the residue level. In recent years, many studies have focused on non-bonded interactions and developed tools to calculate and analyze such interactions. In this study, we present a highly automated approach for the calculation of non-bonded energy. Our strategy invoked protocols relevant to non-bonded interactions within Discovery Studio 2.0 (DS2.0, Accelrys Inc.) bottom module using Perl script, and determined the direct command line operation of calculating non-bonded interaction energy batches without accessing the graphical interface of DS. This approach extended the DS2.0 module and was applied to a recent study of complex structure analysis.
