Dear List,
I am doing MMPBSA calculations on a ligand-receptor system following instruction provided in tutorial 3. After generating MD trajectories in production step (prod.mdcrd) I failed to run MMPBSA.py and am getting the following error messages:
$ MMPBSA.py -O -i mmpbsa.in -o FINAL_RESULTS_MMPBSA.dat -sp com_solvated.prmtop -cp rec_7b.prmtop -rp rec.prmtop -lp lig.prmtop -y prod.mdcrd
Loading and checking parameter files for compatibility...
File "/opt/apps/amber14/bin/MMPBSA.py", line 94, in <module>
app.loadcheck_prmtops()
File "/opt/apps/amber14/bin/MMPBSA_mods/main.py", line 609, in loadcheck_prmtops
self.normal_system.CheckConsistency()
File "/opt/apps/amber14/bin/MMPBSA_mods/parm_setup.py", line 897, in CheckConsistency
raise PrmtopError('Topology files have inconsistent RADIUS_SETs')
PrmtopError: Topology files have inconsistent RADIUS_SETs
Exiting. All files have been retained.
I will appreciate it if I receive help on this.
Cheers,Siavoush
