  1. MMPBSA.py is included in AMBER package ↩↩↩

  2. Without documentation ↩

  3. NMODE = Normal modes approximation, QH = Quasic-Harmony approximation, IE = Interaction Entropy approximation, and C2 = C2 Entropy ↩

  4. We plan to extend gmx_MMPBSA compatibility to MMPBSA.py's results ↩

  5. Currently there is a repository (AmberUtils) for analysing the results ↩

  6. GROMACS 20xx.x is not officially supported. There is a Pull Request that offers a minimum compatibility with versions higher than 2016.x one, but still with limitations ↩

  7. It is not clear whether it does support GROMACS versions 20xx.x or not, but we assume that it does since it is script-based ↩

  8. It is not clear whether it does support APBS versions 3.x.x ↩

  9. gmx_MMPBSA is compatible with AmberTools20, AmberTools21, and AmberTools22 ↩

  10. gmx_MMPBSA supports Linear and Non-Linear PB equations. MMPBSA.py on the other hand, requires the user to modify manually the *.mdin input files ↩↩
