Hi
I'd second NX; you can install a free server for one or two (I think - I only
use one at a time ;-)) concurrent connections and a local client, then it's
almost "like being there".

Dear BBer,

continued success of the CCP4 collaboration and to support its software

Doesn't lsqkab work? It just needs proper atom matching.
Coot definitely does superimpose DNA. One problem is that simple-lsq works on
a single chain, but you can trick it by changing chain id and renumbering the
other strand.
As for helix rotation, you can derive it from rotation reported by

Hi,
not knowing other details, the most naive guess is that this may be a
footprint of mask-based bulk-solvent model. Next one is that you are
contouring at too low/high level (note, sometimes, if, for instance,
solvent content is high, you need to look above/below 3sigma). Of course,
there could

Measuring Angles is another matter, but the superposition services of
the DrugSite will align an arbitrary selection of DNA residues (the
moving molecule) onto a target residue selection on another
structure. The selection can include a duplex, or even a duplex and
some protein residues.
Alright, alright,
I should thank Eugene for being such a good sport. And I should also
apologize for all the work I just created for him!
I fully appreciate all the years and years of effort and struggle that

Respected Sir,
I saw this option in refmac5 - 5.6.0037, (I use
refmac5-5.6.0117), but is this option present in
GUI?
Thanking you

I agree with Nat. There are good GUIs and bad GUIs, just like there are
good command-line programs and bad command-line programs. Bad programs
are easy to write and good ones are hard. Conservation of "work" I think.

What, I'm afraid, people rarely realise these days, is that their desktops are,

Has anyone else noticed a problem with the structure of the N-terminal capsid
domain of HIV-2 PDB 2wlv.
Load it up to in coot and navigate to residue B118.

By the way, you will need to show symmetry atoms to see the problem.

Looks like a typo to me: if you change the CRYST space group record from
P212121 to P21212, as the paper says it is, the packing problem goes away.

Not only 118, look at 119 . It seems also that residues 82-88 incorrectly
placed . I think that authors (if they are reading this board ) must fix
errors. To be honest this is not first time I see such models.

This explains why I cannot reproduce published R-factors (with files from
PDB I get ~40%). If I force my favorite refinement program to use P21212
then I get R close to reported in PDB file header.
This makes it worth reminding that it's rarely a good idea to edit PDB file
out of refinement.

In my opinion pdb must perform more strict checks of structures. I can
remember at least 2 structures without OXT entry for C terminal tail . Of

The CRYST1 in the pdb header is problematic.
CRYST1 95.520 47.815 88.570 90.00 90.00 90.00 P 21 21 218
it looks like the number '1' was paired to the space group rather than the
space grop number (i.e. nr. 18 for P21212)
Table 1 in the paper specifies P212121 as the space group.
i meant to say P21212

It is typo:
R factor for p212121 - 0.4
for p21212- around 0.18

In this particular case attempting to calculate R-factor using data and
