Can I ask a dumb question? Just curious...
Why are we now limited to 80 columns? In the old days, that
was a limit with Fortran and punched cards. Can a record
(whatever it's called now) be as long as we wish? Instead of
compressing a lot on a

The real space refinement can be done either with the tools from

That's easy: Backward compatibility, both in terms of old programs and
old data.
The idea is to maintain as much interoperability as possible.

Correction: Scratch what I wrote -- the PDB format does now support a
formal charge field in columns 79-80 (1+,2+,1- etc.). Hooray!
Thus, adoption of the CONECT valency convention is all it would take for
us to be able to convey chemically-defined structures using the PDB
format.
I'll

Have a look at this very nice paper:

Actually, everything proposed with break some software.
The real question is one of how much value the
community gains from how much of a change. mmCIF
was one proposal that would solve the problem,
but which met a lot of resistance. The change
in atom serial numbers to strings is another
A couple of buccaneer releases have gone by since I last made an
announcement:
release 0.7.2:
- new 'correlation mode' gives better results after MR or when
completing an initial model.
- sequenced fragments are now renumbered to match the position in the
final sequence.

If I may expand on what Eleanor said.
The issue is not the atom labels, but that the atom labels are in the
right place (i.e. the refer to the right atoms).
There is an IUPAC convention on the torsion of CB-CG-CD-OE1 (for GLU).
The torsion should be between -90 and +90. Yours is not.

I guess I did not make it clear. I used the data file for refinement
which is also used for phasing (peak_anomalous.hkl).
Traditionally, people will reprocess the same set of data for
refinement (rescale it in hkl2000 without using the option

I support CCP4 adopting the hybrid36 and 2 char chain id extensions too.
If no-one else steps up to do it, I'll try and patch mmdb to support it

How do I tell Refmac that I have an inhibitor covalently bound to a Ser
residue? I am using the ccp4i interface and this is what I've came up
with (looking through the archives) but it does not seem to work

Folks,
Don't take this as an argument with software people - I have a side note about
structures.
Back in the day when I used to solve Structural Genomics structures, we almost
always knew substitution rate from masspec and Se always refined to lesser
occupancy. Could it be the decay instead?
