[gmx-users] shall we use Charmm_t3p water model?

[Albert]

hello:

   I found that some people use CHARMM27+t3p for their simulation 
system, and some prefer CHARMM27+charmm_t3p. I am just wondering is it 
necessary to use CHARMM_T3P model for a system which introduce CHARMM FF 
for the protein? I found that it is pretty slow to use CHARMM_T3P model.

thank you very much.
Albert
