[gmx-users] Converting Tripos FF to Gromacs?

[serdar durdagi]

Dear all,
   
  I have made MD simulations of fullerene derivatives using Tripos FF, for short simulation time. I would like to extend these simulations using faster program GROMACS.
   
  Is there any way to convert Tripos FF and structure files to gromacs *.itp, and *.pdb files, respectively? (I tried to convert pdb file to gmx *.itp and *.pdb files using PRODRG, but it failed). 

  Best Wishes,

Please leave gromacs-related correspondence on the list. That way it's 
archived for others to find later.

Various force fields have tools that are suited for topology-generation, 
like Antechamber or PRODRG or x2top or pdb2gmx, and your choice of force 
field will be connected with the availability of such tools and the 
nature of your simulation system.
