Dear gmx-users

I'm a novice of GROMACS.

That's fine, but to get effective help you need to construct an effective request. See http://www.catb.org/~esr/faqs/smart-questions.html for ways to do that effectively.

I want to simulate for lipid bilayer with antimicrobial peptide.

I downloaded a lipid pdb from Tielmann's site but I have two questions for MD simulation.

First.
How can I solvate peptide with the lipid pdb ?
Editconf and genbox lead some error.
I think because the pdb of lipid already formed by box type, but I don't have idea.

Neither do we, because you've told us nothing.

Two.
I want to simulate for only lipid using by downloaded pdb.
So I proceeded step by step and I succeeded in energy minimization step.
When I run restraints MD, I showd an error message as follows.

"Check for bad contacts and/or reduce the timestep. ~~~"

Would you tell me what is wrong?

We can't tell yet.

I already search gmx_users mailing list but I didn,t hear from list.
