Hello, a colleague just pointed me to an innocuous sentence in the
ctruncate:
"CTRUNCATE looks for anisotropy in the data and performs anisotropy
correction."
What exactly does that involve...?
phx.
This seems to be very a common scenario in MR and recently we have added
some code to phaser.MRage that would handle it automatically. Each partial
solution is analysed for the presence of (complete of incomplete)
assemblies that obey local point group symmetry. After such an assembly is
identi
Hi,
I find some information here :

And for a more usefull answer, they explain that :
The hbuild statement tries to build the position of any selected
hydrogen based on the position of the heavy atom antecedents (Brünge
For those of you who want to attempt multi-copy problems with Phaser...
Most of the work on Phaser over the last year has gone into improving
results for multi-copy problems, to increase the signal-to-noise of the
searches and reduce the computation time (more solutions for less cpu).
The big
Well - I have found lots of molecules but usually not in a single run.
The first thing to think about is: is this likely to be a dimer? trimer?
tetramer?
Things to consider - a) any non-cryst translation? b) tthe self rotation
might give a clue - c) is the model a multimer, c)what do the biochemist
Hi Leonid,
Thank you for your valuable suggestion. It is exactly the case. When I
tried P21, it works well. The solution is now very clear.
Best,

There were many complaints that Phaser was too strict in its packing check, so
since version 2.3 (the one with the soon-to-be-updated version of CCP4), Phaser
has by default allowed up to 5% of the trace atoms to clash. In more recent
versions (available with Phenix and soon from CCP4), if some
