(1). Can I say the X-ray weighting is optimal when it yields the smallest
Rfree, meanwhile RMS-Z(bonds) is smaller than 0.85 - 0.146*resolution
(angles also maybe)?
The weighting is optimal when the free likelihood is maximised with
respect to the weights, or equivalently when the negative log

Hi,
I am trying to install mrbump on a 32 bit ubuntu linux desktop (kernel:
2.6.31-22-generic, python 2.4, 2.5 and 2.6 tested). When executing
python setup.py after extracting mrbump-0.4.4, I get the following
error messages:
setup.py:269: DeprecationWarning: os.popen4 is deprecated. Use
Hi Ian,
First, constraints are just a special case of restraints in the limit
of infinite weights, in fact one way of getting constraints is simply
to use restraints with very large weights (though not too large that
you get rounding problems). These 'pseudo-constraints' will be
I agree with Gerard. Example: it's unlikely to achieve a result of
rigid-body refinement (when you refine six rotation/translation
parameters) by replacing it with refining individual coordinates using
infinitely large weights for restraints.

I had trouble adding image files into iMosflm (1.0.4) GUI running on our

Dear colleagues,
We want to buy a macbook pro 13. It has Nvidia Geforce 320M graphics. Has
anyone tried this computer and graphics with coot, O and Pymol and what is
the performance?
We would appreciate all suggestions.
