Force field conversion
AMBER to XPLOR
This is a conversion of AMBER force fields to XPLOR format. It is recommended to load the force fields in XPLOR with the provided toppar stream files, to avoid mixing incompatible topology and parameter files. Force fields included are:
- toppar_ff94.str corresponds to leaprc.ff94
(Cornell topologies with parm94) - toppar_ff99.str corresponds to leaprc.ff99
(Cornell topologies with parm99) - toppar_ff99SB.str corresponds to leaprc.ff99SB
(Cornell topologies with parm99 + frcmod.ff99SB) - toppar_ff99bsc0.str corresponds to leaprc.ff99bsc0
(Cornell topologies with parm99 + frcmod.ff99SB + frcmod.parmbsc0)
The archive contains the topology and parameter files for XPLOR as well as a README file explaining the technical details and reliability of the conversion, and examples of peptide and nucleic acid building.
