Thank you Jason,

I installed parmEd and used your script;

import parmed as pmd

amber = pmd.load_file('prmtop', 'inpcrd')

# Save a GROMACS topology and GRO file
amber.save('gromacs.top')
amber.save('gromacs.gro')

but got error:

raise GromacsError('Structure has mixed 1-4 scaling which is '
parmed.exceptions.GromacsError: Structure has mixed 1-4 scaling which is not supported by Gromacs

I used leaprc.ff14SB and leaprc.GLYCAM_06j-1. Do you have any suggestions for me?
