No - not completely. Better to at least start from matthews_coeff and get a guestimate of the expected number of copies. Presumably you know the sequence of your crystal.
A native patterson can show a non-crystallographic translation. A self-rotaton may suggest something, but best to start from the simplest point - viz matthews.
