[gmx-users] A converter for lammps to gromacs

[X Rules]

Hi, 
 I am interested in switching from LAMMPS to gromacs. However, I have been trying to see if I could find a tool that could convert a lammps data file to a gromacs topology and a starting gro file which can help me setup the system. Is there something like this which exists already? or How shall I go about doing it? (I would like to avoid changing r2t, itp etc files, wherever possible)
Thanks,
