Thanks for your advice.

And because I do not care about information of the water and the ion much, I 
prefer to use trjconv with -n index and -force option to generate a new trr 
file for my protein and/or nucleic acids only.


If I name a molecule in my itp file with the same word for some atomtype or 
residue name, e.g. "ADE", will this cause some conflict?

Thanks a lot in advance.
