A short introduction to ACPYPE

ACPYPE is a tool based on Python to use Antechamber to generate topologies for chemical compounds and to interface with others python applications like CCPN tools or ARIA.

acpype is pronounced as "ace + pipe".

Topologies files to be generated so far: CNS/XPLOR, GROMACS, CHARMM and AMBER.

Latest version of ANTECHAMBER can be found in AmberTools 12.

NB: Topologies generated by acpype/Antechamber are based on General Amber Force Field (GAFF) and should be used only with compatible force fields like AMBER and its variants.

Several flavours of AMBER FF are ported already for GROMACS (see ffAMBER) as well as for XPLOR/CNS (see xplor-nih) and CHARMM.

Please, read ACPYPE Wiki pages for more information.

ACPYPE was inspired by: by Eric Sorin, David Mobley and John Chodera;
Elmar Krieger's YASARA Autosmiles;
topolbuild by Bruce Ray;
xplo2d by G.J. Kleywegt.
