[gmx-users] genion

[Alberto Malvezzi]

Dear Collegues,
I know his subjec has been discussed alredy, but I still havent got the 
answer.
My system has a charge of -12.
If a use genion with no -random flag, all Na ions are placed on the box 
wall.
If I place the -random flag genion works fine, that is, randomly places 
the Na ions around the protein.
But I was hoping to to place the ions based on the electrostatic 
potential, not randomly!
What am I doing wrong?
Thanks
Alberto
