But you can insert TER where you want an interruption in sequence and
then build an explicit bond between the respective residues.
My student did that the following way:
e.g.,
r1
r2
TER
r3
r4
TER
r5
then bond r2 r4
and bond r3 r5
of course the usual care of choosing the right atoms needs to adhered
to.
