[gmx-users] position restraint on a plane

[Myunggi Yi]

Thank you.

I'm a beginner.
How can I setup the restrain?
Where should I get the information.
The manual is not enough for me.
The position restraint .itp file dosen't seem to offer for the reference (z=
1.0) option.
Whould give me more detail?
