Maybe this is a different issue... but it's ok that after the 99,999th atom the counter restarts from zero?

 21374SOL     OW99999  12.986   9.021   7.036 -0.0037 -0.4345  0.3977
 21374SOL    HW1    0  13.069   8.987   7.081  0.5916  0.5409  0.0638

Could this be the origin of my problem?

Thanks again,

Fabio

Were the molecules whole in the coordinate file you replicated? If
not,
the bonds will now be assigned across the entire box.

Yes and not, depending on what you mean by "whole".
It is an ion channel, so it's made of four chains.
This clarifies? (i guess not..)

By whole, I mean that the molecules are not split across periodic
boundaries in the initial configuration that you replicated. If you
replicate a periodic break, then you split the molecules by a distance
equal to the new periodic distance.

Ok, so: no, it's not broken.


What you need to do is use the information mdrun provided you to
diagnose what's going on. Apparently atoms 193657 193660 are separated
by 31 nm. What are your box vectors? Where are these atoms in the
system? Then you'll have your answer. The only reason I can think of for
such extreme distances is a periodicity issue.
