There is a program in the CCP4 Suite called "reforigin", which might be
what you want. Since all origins are equivalent, there is no way
a-priori to force an MR program to always use the "same origin", all you

Both pymol/align and coot/ssm (I presume) do the secondary structure

proteins. In Pymol, there is "fit" command that instead matches atoms
with the same names; and "super" which does sequence alignment first.

If using Coot, you can also "merge molecules" on the original and all symmetry
related pdb files that you saved, which will automatically renumber the chains
for you.

Hi Mike,
By 'align', if you mean superimposition, lsqman will do the job.

Hi all,
I will highly appreciate your help regarding following:

( I tried regular "align" in Pymol, but it doesn't work for DNA; it

Thanks a lot in advance !

Hi
Mosflm has done this for years - there's a recipe on the Mosflm FAQ
pages (well, the questions were asked frequently when I originally
wrote them about 7 or 8 year ago!). Someone called Graeme Winter (now
at Diamond) wrote this code originally...)

Hello FX,
As already mentioned there a number of programs that can perform this task.
If you end up deciding to go with Coot, I put together a play by play that
should help.

Hope that helps.

Hi Andy,
If you have a recent CCP4 installation (i.e. 6.something I think)
there's diff2jpeg, which does exactly what you want. Otherwise there
are also spells to use Mosflm for this which allows a little more
control over the greyscale settings.
Cheers,
Graeme

There is the shift_molecules.inp script in CNS. You can definitely do
this manually using pymol and/or coot. PHASER, I believe, does this
automatically.
