Hi Luke,
the new imosflm is really wonderful with its easy access to mosflm,
its plenty graphic diagnostics and the quick pointless/scala access.
A couple of questions that came up using it during data collection:
- Is there any imosflm-specific documentation?
- Is there a possibility to read
Robbie,
Thanks, this looks like it was pretty close to what I was looking for.

A few years back I built 6 machines for $8000 total, and it should be
as cheap if not cheaper now. I bought my video cards on ebay (there
are lots of people who part out old leased machines and so it is very
cheap really, and I haven't had a card fail yet, knock on wood). I'll

Dear Anna,
Here's my personal list of preferences for a fast and pretty inexpensive
Linux workstation for crystallography. I can provide exact specs if desired.
This assumes that you or someone in your group has basic computer hardware
skills to put the workstation together*.

Hi Anna:

Thanks for all the suggestions.
If I would try to accelerate the formation of the crystals by microseeding, do
you think these soft/non-diffractionable crystals can help?

I think it is just chosen to keep the numerical range reasonable, and to
be easy to remember..
There is no signifance in any scale at the truncate stage - it will only
be properly given when the model is refined..

Eleanor,
Any ideas if the 0.01 in truncate is just being used as "arbitrary small
number to prevent overflow", or if it's serving another purpose? I
wasn't sure from reading truncate.f.
Thanks,

Is there an easy way to do this for NMR data? For x-ray data, it's
relatively straightforward to re-calculate a map using the deposited
model and amplitudes, whic
Hi Marc
Sorry it's taken me so long to get back to you on this, I've had it on
my mind for a while that your comments deserved a response, but you
raised many interesting points and it seemed that the objections that
you raised to what I was doing required that I think more carefully

Rigaku X-ray system for sale.
Due to the acquisition of new X-ray crystallography equipment Imperial
College London has a complete X-ray diffraction setup available at an
extremely reasonable price.
The specification is as follows:
Rigaku RU-H3RHB rotating anode generator
Osmic blue optics

Answer is NO to difficulty; H32 is no easier or harder in principal than
any other SG..
However do you have a NCS translation? or twinning?
Is your model likely to be an oligomer?

MOLREP was used to test a set of SGs and found a good solution in one of
them; P2 21 2 for example.
But the refinement against the original data stuck.. The explanation is
this:
Although the MOLREP wrote
