Also, ':1<:Cl-3.6' is not a valid distance-based mask. You probably want
something like ':1<:3.6&.Cl-'; see section 8.2.3 "Atom mask Selection
Syntax" of the AmberTools 13 manual for more details. Note that the
distance-based mask uses the active reference structure in parsing the
mask, i.e. it does not update on a frame-by-frame basis.
