I would like to add my comments that Sharp & autoSharp are great
programs that produce excellent phases, and that installation isn't
too hard (even though the whole setup does seem unnecessarily
complicated :-) )
I would also like to say that the Global Phasing people, in particular
Clemens Vonrhein, are extraordinarily helpful and respond quickly to
any query about the software
On the original question that started this thread, as far as I can see
there doesn't seem to be a Mac OSX intel version available, publicly
at least
Thanks
