Previous version: ff-nucleic-OL15 (OL15 DNA force field, including OL3 RNA force field)
ff-nucleic-OL15 force field is ff99bsc0 plus the following Olomouc dihedral refinements:
| DNA | ||
|---|---|---|
| χOL4 | refinement of DNA glycosidic torsion chi | [6] |
| εζOL1 | refinement of eps/zeta torsions | [7] |
| βOL1 | refinement of beta torsion | [8] |
| RNA | ||
| χOL3 | correction for RNA glycosidic torsion chi | [4,5] |
AMBER:
Parameters can be used in AMBER16/AmberTools16 (and newer) by sourcing files in tLeaP: leaprc.RNA.OL3, leaprc.DNA.OL15
**************************************************************************************************************************
Alternatively, ff-nucleic-OL15 may be downloaded here
Parameters may be read into tLEaP using command: tleap -s -f leap-ff-nucleic-OL15.in
Files are prepared for use with AMBER 14. Note that all downloaded files should be placed in the current directory (from which tLEaP was launched) or you should define the path to these in leap-ff-nucleic-OL15.in
