I'm well aware of that. Since I'm looking for outliers in the PDB, avoiding
2HR0 is the opposite of what I want to be doing. ;)
I only picked it for my example because it's one of a few IDs I have
memorized. :)

Hi,
2HR0 I would stay far away from that one! It is a made up model, not
based on any real data. Unfortunately, for reasons unclear to me, this
structure has still not been retracted from the PDB. This B factor could
just be a figment of the senior authors imagination
Dear professor George Sheldrick,
I am so sorry to bother you again!
From the shelxc_fa.lst file, we can find that the Patterson peaks will be
selected only when the 'Mult' equal to 1..
shelxc_fa.lst:
Patterson (* indicates vector selected for search)
X Y ZHeight Mult
That's because they are Harker peaks which for good reasons are
unsuitable as translation search vectors. The Patterson function is well
explained in many of the standard crystallographic texts (e.g.
Giacovazzo's book that I already recommended) and maybe you need to read
these before asking your

We announce a call for synchrotron beam time applications in biological
small-angle scattering (SAXS) and macromolecular crystallography (MX).
The beamtime will be available at the PETRA-III storage ring from
March, 1st, 2013 to June, 30th, 2013.
In biological SAXS, we offer

around for long time archival, i.e. computer -- Sumerian (or Babylonian) clay.

In terms of information density clay, paper and suchlike are not likely to

* Areaimol: Fix for already allocated array
Hi,
Seems not officially retracted from Nature either. On the paper's web page,
there was only a line in small font read like this:
There is a Brief Communications Arising (9 August 2007) associated with this

It took me more than half an hour to find this line. I normally won't

Sorry Eric I don't have an answer for your question.

From the University's announcement (

It's hard to believe this has gone on so long, but the situation doesn't seem
to have changed since the wwPDB put up a statement about this case in December

entries are only made obsolete when the corresponding

This is probably a really bad question, but are there any examples of Trp

Thanks and sorry for the offtopic question.

When last I checked a few months ago, of the 12 implicated structures only
4 had been moved to the PDB's repository of obsolete structures.
