You use TFE in a wet lab to physically induce helicity in real life. For a simulation, there is no guarantee that the forcefield you are using will behave in the same way. Might as well just use distance restraints to force the helicity. > I have never performed simulations using micelle.

Do I require lipid.itp for this simulation? you say you already have a .itp for SDS that works your chosen forcefield? -- gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting! * Please don't post (un)subscribe requests to the list.
