Hi,
I afraid for very large molecules it may take a lot of memory. This is
because internally the procedure generates and accumulates hundreds if
not thousands maps.. You can try to make these maps smaller by changing
resolution_factor=1./4
to
resolution_factor=1./3
which may diminish the efficacy of the protocol but that's the only
suggestion I have (apart from trying it on a "bigger" computer).
