Dear Gromacs Users,
I created a starting structure that includes 100 n-dodecane molecules ( pdb file ) using packmol. And I want to use the packmol pdb file in Gromacs 3.3 . Can I directly start generating Gromacs top and crd file with using pdb2gmx ? For example to use a packmol pdb file in Amber it

As long as you have a suitable topology, you do not need to use pdb2gmx (which probably doesn't have an entry for n-dodecane in any of the force fields, anyway).

is necessary to add TER cards betwen each seperate molecule. Are there anything like that I must do for using packmol pdb file in Gromacs ? And units in packmol pdb file is angstrom . So Should I convert units to nm

Gromacs can use .pdb files as input.

? Finally What is the latest stable version of Gromacs ? I think Gromacs 4.0.3 is still a beta version ?

Version 4.0.4 is the latest stable version (4.0.3 was not a beta, either).

Thanks in advance!
Regards
