I have performed a simulation for a protein-metal cluster complex system for 500ns. While calculating MMPBSA analysis for the system, I had selected two ranges of Trajectory period (100-110 ns; 290-300 ns) based on RMSD profile of protein-metal cluster 500 ns simulation period and executed the commands for a single range of trajectory period. In the result of the binding energy of my system, values are void. Hence, I Kindly need your valuable suggestions in this regard. Herewith I have attached the obtained results of my system,
#Complex Number: 1 =============== SUMMARY =============== van der Waal energy = -1144.250 +/- 28.405 kJ/mol Electrostattic energy = 0.000 +/- 0.000 kJ/mol Polar solvation energy = nan +/- nan kJ/mol SASA energy = -25.841 +/- 1.107 kJ/mol SAV energy = 0.000 +/- 0.000 kJ/mol WCA energy = 0.000 +/- 0.000 kJ/mol Binding energy = nan +/- nan kJ/mol =============== END =============== *Saranya Vasudevan,* *Research Scholar,* *Molecular Quantum Mechanics Laboratory,* *Department of Physics,* *Bharathiar University,* *Coimbatore-46* -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
