[gmx-users] Changing Ionic strength in gromacs

[Miguel Machuqueiro]

Hi all,

I would like to know how can i change the ionic strength of my simulation 
when using Reaction-Field.

The manual only refers to the Generalized-Reaction-Field and mentions:

"The ionic strength is computed from the number of charged (i.e. with non 
zero charge) charge groups"

OK... not what I wanted, but let's give it a try...

Running a simulation with it, I observed from the MDP_output (-po option of 
grompp) in the Generalized-Reaction-Field section that the Ionic Strength ( 
I ) was still zero.

Any ideas?? I'm I looking in the wrong place?!

Thanx in advance,
