Dear all,
I built a complex of GPCR and a small molecule ligand (X), then inserted them into a POPC membrane. After 20ns' MD, I tried to use MMPBSA.py to calculate the delta binding energy. Topology files are complex+Membrane+solvated, complex, GPCR and ligand (X). The topology files are generated from complex+Membrane+solvated by ante-MMPBSA.py, or by the pdb files before inserting complex into membrane.
However, the calculation failed. The error occurs during GB calculations, for mmpbsa_py_energy or sander. There's no more debuging information even in the temporary files.
So, is there someone who met this error before? Or, can someone provide a way to calculation binding energy in membrane system?
Thanks a lot.
