Dear Thomas,
Turning off the angle works!! I have the output written and also I have
confirmed the distances using ptraj as well.
Can you please explain me regarding how I can interpret my result from as
shown below (first two line of the output are only shown).
What does the number in the parenthesis beside the distance,angle values
mean. Is it the deviation?
What does lifetime and maxoccupancy give me?
atom# :res.atom atom# :res.atom atom# :res.atom %occupied
distance angle lifetime maxocc
