Dear gromacs user,

I practiced of MD stimulation with LysoZyme tutorial. Now, They used 15:
OPLS-AA/L force field and also i saved all *.mdp* file (ions. mdp, md.mdp,
nvt.mdp, npt.mdp, minim.mdp, etc.) as given in tutorial and successfully
performed MD stimulation.

Now, I have want to study my protein. I found force field 9 to 14 are
reported for my protein in literature. Further, I also tried it and found
"Residue 'ZN' not found in residue topology database" only for force field
15 (OPLS-AA/L force field), not for any other force field (9 to 14).

*Now, I have two questions.*

*1) Can i use this file for stimulation study with other force field (9 to
14)? If not, from where i get them?*
*2) Also want to study MD at higher temperature, still Can i use tutorial
.mdp files? or what informations i have to change in files (.mdp)*

Can any one tell me what to do?
