The problem of course is that the delicate signal of such a 'hidden'

Dear James,
About 30 years ago I wrote a clone of the program ORTEP; the clone
was called XP, but unfortunately Microsoft later stole the name
and brought it into disrepute. So that I would always be able to
see at a glance which plots were 'genuine ORTEP' and which were
my clone, I built in a s
Hi James
I think the answer to your question about the 'R-factor gap' is easy to
answer (but not so easy to solve!). It's obviously due to the
inadequacy of our models, particularly with regards to thermal motion
(anisotropy, anharmonicity etc), disorder & motion correlation/diffuse
scatter, also
Yes, Harry, indeed there is a program for simulating diffraction
patterns. You can get a development snapshot of it here:

MLFSOM (mosflm in reverse) is not the only program of its kind in
existence and I don't think it is a go
