Re: [gmx-users] Parmbsc1 force-field
Hi Dan, No, it can be confusing. After reading your email I even dug up an old email thread where we (confusedly) discussed this topic. Most importantly is to not use the Na-parameters that I think are by default present in the gromacs implementation, which leads to ion crystals (DOI: 10.1021/jp0765392). The two references you cite, Smith & Dang 1994 and Dang 1995, are quite similar. I emailed with parmbsc1 developers and their experience was the same. Together with parmbsc0, other authors have used Dang 1995, so that's how our choice came about. To follow the parmbsc1 authors you should indeed use the paper they cite. -- Viveca On Mon, Mar 5, 2018 at 4:49 PM, Dan Gilwrote: > Hi Dr. Lindahl, > > Thanks for putting the force-field together!

Re: [gmx-users] Parmbsc1 force-field
Hi Dr. Lindahl, Thanks for putting the force-field together! It is helping my research very much. Right now I am just checking over everything to make sure I didn't make any silly mistakes, and that everything is justified. I might be just confusing myself, but the parmbsc1 paper is citing this paper (http://aip.scitation.org/doi/pdf/10.1063/1.466363) for the Na+ parameters... whereas the citation for the force-field you put together is this one (https://pubs.acs.org/doi/abs/10.1021/ja00131a018). They have different values for the 12-6 sigma and epsilon. Same authors, but the one you chose is a newer work than the other one. Is that why you chose the parameters from this paper?

Hi Dan, I'm the author together (with Alessandra Villa). I hope it helps others providing the parameters on the website, but as Mark said, it's up to you to double-check it.

Re: [gmx-users] Parmbsc1 force-field
Hi, This is not an official GROMACS offering, so as always, buyer beware. But the forcefield.doc file notes the source of the Na+ parameters as https://pubs.acs.org/doi/abs/10.1021/ja00131a018.

Re: [gmx-users] Parmbsc1 force-field
Hello, update here. I think there is a possibility that the parmbsc1 force-field updated on the gromacs website has some incorrect values. In the parmbsc1 paper (https://www.nature.com/articles/nmeth.3658.pdf) they say they use Na+ parameters from this paper ( http://aip.scitation.org/doi/pdf/10.1063/1.466363). .sigma (Å)epsilon (kcal/mol) Na+ 2.350 0.1300 Here is what I find in the GROMACS force-field. .sigma (nm)epsilon (kJ/mol) Na+ 0.25840.4184 I would like to directly contact the author, but I have no means at the moment.

[gmx-users] Parmbsc1 force-field
Hi, I am using the parmbsc1 force-field (http://www.gromacs.org/@api/ deki/files/260/=amber99bsc1.ff.tgz) in GROMACS. I am looking for the original paper where the Na+ and Cl- ion 12-6 Lennard-Jones are coming from, but I am having trouble finding them. The Amber17 manual suggests that this paper ( https://pubs.acs.org/doi/pdf/10.1021/ct500918t) is the source for monovalent ions. But, the values from the GROMACS parmbsc1 force-field (ffnonbonded.itp) does not match the values from the paper, I think. Could you point me to the right direction? Citing the original paper is something important to me, but I have apparently hit a dead end.
