ParmEd is a package designed to facilitate creating and easily manipulating molecular systems that are fully described by a common classical force field. Supported force fields include Amber, CHARMM, AMOEBA, and several others that share a similar functional form (e.g., GROMOS).
ParmEd is capable of reading and writing to a wide array of different file
formats, like the Amber topology and coordinate files, CHARMM PSF, parameter,
topology, and coordinate files, Tinker parameter, topology, and coordinate
files, and many others. The expressive central data structure (the Structure
class) makes it easy to quickly and safely manipulate a chemical system, its
underlying topology, and force field parameters describing its potential energy
function.
There are two parts of ParmEd---a documented API that you can incorporate into your own Python scripts and programs, and a GUI/CLI pair of programs that provide a means to quickly perform various modifications to chemical systems for rapid prototyping.
The API also provides bindings to the OpenMM library, permitting you to carry out full molecular dynamics investigations using ParmEd on high-performant hardware, like AMD and NVidia GPUs.
The following people have contributed directly to the coding and validation efforts in ParmEd. The primary developer is listed first, followed by the other contributors in alphabetical order. And a special thanks to all of you who helped improve this project either by providing feedback, bug reports, or other general comments!
