Using a flexible reference to generate a PMF is certainly not a good
More than affecting your convergence, your distance may have only little
to do with the actual position of your ion in the channel. Imagine the
in a stable position and has to go over some energy barrier. It likely
loop will move instead of your ion ...
You might want to change your the reaction coordinate.
