Hi,
I have asymmetric unit cell CIF file. I am using pymol to generate supercell of the structure and using pdb2gmx command to obtain gro file. I am seeing only one ring in gro file while the rest of the rings are missing and hence supercell as well. Do i need to use any other tool or command so that Gromacs can access entire supercell structure. Is there anything which is needed to be specified for symmetry of the cell?
