Thanks for your reply.
You are right. I should not extrapolate too literally from your tutorial
to my system.
But, I have a general question:
There is 2 groups in COM pulling method (reference group + pull group).
If I want to use pull_geometry = distance, so, I should fix reference group
to be immobile. Is it true?
What you described earlier should not be attempted with "distance" geometry. It
won't work very well. The use of restraints is almost NEVER necessary,
especially in the case where the reference group is much more massive than the
On the other hand, I want to know exactly using position restraining on
reference group is optional or mandatory in COM pulling method?
Almost never used. More explicitly - you do not need position restraints.
