Dear all,
thank you very much for your kind suggestions.
my crystals are very anisotropic, and usually about 1A between the two
different orientations. here, I post a brief statistic table treated by
HKL2000. In fact, I am mainly working on the crystallization and
characterization of

Dear Martyn, Pavel and other interested,
I think, an official extension by the PDB to two characters for the
chain names and 5 digits for residues would really help. I'm currently
working on a structure with 6x15 chains (through NCS) - it is huge and
only a few programs can handle this by

Hi,
There have been many discussions along these lines over the years. The problem
is understood well. The favoured solution is the use of mmCIF (as posted
several times on the BB). But I would rather leave it to those officially
involved to comment on the pros and cons. On the practical

We sort of take this for granted now that we have automated

Dear Dhana,
if you used refmac5 or phenix.refine, these data ought to be in the
header of the PDB-file you are submitting to the PDB.
Best,

Dear Yu,
I hope you have somebody in your lab to share their expertise with
you, because you will benefit to a much greater extend in learning
data integration from somebody sitting next to you than from the
limited possibilities of online resources.
Hi Frank and Ian,
We struggled with the small changes in free R-factors when we implementing
the paired refinement for resolution cut-offs in PDB_REDO. It's not just the
lack of a proper test of significance for (weighted) R-factor changes, it's
also a more philosophical problem. When should you
Hi Martyn
can you give me a reference where the rationale for this preference for
mmcif is set out? I tried a pubmed search but cannot find anything.
thanks
