WebApr 13, 2024 · GAFF2 was used to model the ligands. The partial charges of the ligands were obtained by the AM1-BCC charge model [ 51 ]. The starting structure of the ILPR G4-ligand systems in the unconstrained MD simulation was fully optimized in the gas phase at the GFN2-xTB level of semiempirical density functional theory [ 52 ].
WebOct 28, 2024 · Then, I used parmed to convert the amber prmtop and rst files to gromacs topology (top) and coordinate (gro) files. So, now I have 4 files which are enough to run the simulations with gromacs. These are WT.top, WT.gro, K2A.top and K2A.gro. I read the documentation of genlib and it seems I have to give the path to the forcefield files. creating line charts in excelWebJul 1, 2024 · All GROMACS optimizations were terminated once the maximum force became smaller than 0.004 kJ ⋅ mol-1 ⋅ nm-1, using a conjugate gradient algorithm.
