[gmx-users] conversion from amber (prmtop and inpcrd) to gromacs itp and gro

[Qinghua Liao]

Hello,

You can also do it with parmed from Amber, here are the python commands:

import parmed as pmd

#convert prmtop and inpcrd into top and gro
amber = pmd.load_file('1N55_apo.prmtop','1N55_apo.inpcrd')
#
amber.save('topol.top')
amber.save('ions.gro')
#
