[gmx-users] how to set pull_rate

[Qian Wang]

Hi,
 
I want to use pulling code. But I do not quite sure the meaning of pull_rate. User guide saies this is the rate of change of the reference position. So if I set this value to 0.0001, does it mean the reference postion will move 0.0001 nm/ps ? If yes, how to define the moving direction? Generally speaking, how to choose the value for this parameter? Thanks very much.
 
Qian
