[gmx-users] Solvatebox from itp GAFF organic solvents and amber solute.

[Sharapa]

Dear users and developers of Gromacs,

I am new in MD in general and in Gromacs particulary.
I want to make MD of small organic molecule in few organic solvents.
My molecule containes Si and I made GAFF parameters for it. I would like 
to use GAFF in my simulation, expecting it to be not too bad for 
describing my system (that also contain pi-pi stacking).
So far using ambertools I have .frchmod and prmtop files for my solute. 
I found .itp GAFF topology and .pdb GAFF Liquid structure files for 
solvents that i am interested in on http://virtualchemistry.org/ site. 
Nevetherless i still dont see the way how to create solvatebox with 
solute starting from data described above. I didn't found a tutorial 
describing similar procedures. If anyone can recommend me anything - i 
would be extremely thankful.

Thanks in advance,
Dmitriy.
