Hey, > [@Eduardneu](#): > > Doing some further research a came across [this website](https://computecanada.github.io/molmodsim-md-theory-lesson-novice/aio/index.html#how-to-choose-the-appropriate-cutoff-distance) that explained how to choose the appropriate cutoff distance. For the AMBER force field, it is 10 Å or 1 nm. The cutoff value depends on the cutoff which was used during the parametrization of the force field. As stated in the primary literature [ff99SB](https://onlinelibrary.wiley.com/doi/10.1002/prot.21123), [ff14SB](https://pubs.acs.org/doi/10.1021/acs.jctc.5b00255), [ff19SB](https://pubs.acs.org/doi/10.1021/acs.jctc.9b00591) and [lipids21](https://pubs.acs.org/doi/10.1021/acs.jctc.1c01217) were all parameterized using a cutoff value of 10 Å or 1 nm, respectively. In case you are working with ff14SB, I think that one uses 8 Å cutoff for non-bonded interactions: “Nonbonded interactions were calculated directly up to 8 Å.” from the ff14SB publication. Please correct me if I am missing something. Regards Daniel --- _[View the full topic](https://gromacs.bioexcel.eu/t/mdp-parameters-for-non-bonded-interaction-using-the-amber-force-field/6458)._
