Hi guys,

i'm stretchin' a protein with gmx; i'm not sure about
the value of the spring constant... how to set it
I've read a couple of papers where they describe SMD
pulling, and they chose the spring constant from this


what is this equation about? where can I find sth that
explains the theory behind (the formula above) a
correct setting of k?
thanks a lot
