So, if you load the SAME coordinate file with the regular topology it
looks ok ?
My only possible guess would be that chimera decided about distances,
etc based on the atomic mass and NOT on the atom type. If that is the
case, there is nothing you can do, except tell the chimera developers to
change that.
