title: Is there any way to convert lammp_file.data to Gromacs files (top and gro), if not then to or to CHARMM files (psf and pdb)?
body: <p>I have a lammps_file.data and I need to convert it to Gromacs files (gro and top) to run my simulations. 
  Does anyone know how to do this?
  Another choice is to convert from lammps to charmm files (psf and pdb). Once I get the charmm files I can just use Topotools to get the gromacs files I need.</p>
  
  <p>Thanks</p>
