Re: [AMBER] Does anyone here use a99SB-disp force field and how did you obtain it?

Hi Homeo,

I obtained the force field files by simply writing to the first author of the paper (Dr. Robustelli).

Anyway, up to my knowledge, the force field is tested and validated only for Desmond Maestro; there is also a less tested GROMACS version, but it is not available for AMBER.

Hope this helps,

Hi Homeo,

Some times the changes that the author made to the force field are not
substantial and instead of providing a package with the force field they
provide a table with the changes that they made so you can make the changes
and generate the new force field.
This is the case here. Look in the SI for the table with the parameters
that were changed then make the changes to the base (a99SB-ILDN) force
field that they used.
