Any 3-point water model will be fine for generating solvent coordinates - the standard practice in GROMACS is to solvate with spc216.gro (per man genbox) and then in the .top file to #include "tip3p.itp" Mark ___ gmx-users mailing listgmx-users@gromacs.org http://www.gromacs.org/mailman/listinfo/gmx-users Please don't post (un)subscribe requests to the list.

Re: [gmx-users] genbox peptide-membrane simulation
Maite, The option -d sets a distance to be met on all sides, considering all the atoms to in the ouput selection. That's not what you want for a membrane now, is it? So, you don't want that option. You should have a box from the lipids anyway, I guess (used to equilibrate that system), just extend the z-coordinate (third number in the last row of the .gro file) such that your peptide fits in. Furthermore, molecules can't go out of the box, there is no outside! There's only wrapping from one side to the opposite one. Please read the manual and the mailing list regarding periodic boundary conditions (and setting up membrane-peptide simulations).

I don't want to solvate the system in x and y axes due to the interaction betwen lipids and water. I did it whit editconf -f input.gro -o output.gro -bt triclinic -c -box 4.936 4.408 12 , but i didn't use the -d option. Is that ok? So my question is: Can I do something whit -d and -box option of editconf program for resulting in a system that it doesn't solvate in x and y axes, and the molecule isn't out?

I guess not, then how to simulate such system? you can use g96 files instead. ...or just restart the numbering of residues or atoms from 1 when you hit the column width. This is particularly useful for PDB files, if you want to visualize a large system in PyMOL/VMD.
