[gmx-users] How to port the parmbsc0 correction to gromacs?

[ÏéÇ« ¿×]

Dear GMX users,

  As parmbsc0 force field significantly improve the representation of alpha/gamma torsions in nucleic acid simulations,i thus want to use the combination of parm99sb+parmbsc0 in Gromacs that was frequently employed in recent publications. However, when i searched the whole forum, i can rarely find any hints for how to do this. Could someone be so kindly to give me a step-by-step guide for the porting parmbsc0 corrections to a exsiting AMBER forcefiled (such as parm99sb) in Gromacs?

 Thanks in adcance!

 Best regards!
