Ah, your problem is the ".LYS" specification in the middle; you do not
want this. Without this, it should work, and if it doesn't either the
parsing routine is messing up or you have other residues in that range
that have NZ or HZ1 atoms (but not the other).
To avoid the potential for "messing up", try breaking up the
specification:
acceptor mask :1-134.NZ :1-134.HZ1
acceptor mask :410-524.NZ :410-524.HZ1
(no .LYS: . is atom name)
Finally, if you still blow memory, what I tend to try is to create inputs
with fewer donors (or acceptors) and run the analysis twice (i.e. first
time with :1-134 and second time with :410-524).
