and pullx data from the first sample config and both contain only one

I haven't used the 2018 pull code yet. Presumably this is correct, just
the distance rather than all its components, though that would be a
change from previous versions.

Did you mean pull_group2_pbcatom? In my case:
pull_group1_name = K
pull_group2_name = CNT
The language for 5.1 pull is (you be the judge on how clear it is):
(0) The reference atom for the treatment of periodic boundary
conditions inside the group (this has no effect on the treatment of
the pbc between groups). This option is only important when the
diameter of the pull group is larger than half the shortest box
vector. For determining the COM, all atoms in the group are put at
their periodic image which is closest topull-group1-pbcatom
A value of 0 means that the middle atom (number wise) is used. This
parameter is not used withpull-group1-geometrycylinder. A value of
-1 turns on cosine weighting, which is useful for a group of
molecules in a periodic system,/e.g./a water slab (see Engin et al.
J. Chem. Phys. B 2010).
Indeed, my group2 is a membrane that is wider than the shortest
half-box. I am assuming it would be a single atom belonging to the
Yes, pull_group2_pbcatom, not 1.
