[gmx-users] Question about COM-Pulling

[Christian Mücksch]

Dear users,

I've got a short question regarding com-pulling. From what I understand 
Umbrella pulling is the same as AFM pulling using a harmonic potential.

Why is the position of the spring in the pullx.xvg not printed? One can 
only find the vector between both pull groups. I looked into older 
Gromacs manuals and in versions < 4 it seems as if this data is printed 
to the pullx.xvg file or something similar.

With kind regards,
Christian
