[gmx-users] Gromos54a7 FF

[Alex]

Dear all,
I would be so appreciated if anybody could give me the Gromos54a7 force
fields for Pluronic L-31 surfactant (OH-[C2H4O]_2-[C3H6O]_16-[C2H4O]_2-H)?
PDB file of the molecule is in below links.
Using topolbuild I am able to get the oplsaa FF, but topolbuild just
removes all the H atoms with the gromos54a7 FF.

Thank you.
