Hello,
I have a refined 1.8A structure that I wonder if I could squeeze out some
anisotropy information. I did TLS refinement on the protein, and it helped my
Rfree. But I would like to ask a biological question based on the thermal
movement of only a few waters (7 total). In theory, that is
Dear developers,
I wonder if the restrictions for MBATCH=1000 in CCP4-v6.0.2 and for scala
(maxbat=1000,maxpmr=2000,maxmat=1000, maxrun=3) hold also in V6.1?
Otherwise I cannot use the precompiled versions and have to recompile!?
Thank you,
Jürgen
Hi Frank,
thanks a lot for your comments, since they raise some interesting
points.
R_pim should give the precision of the averaged measurement,
hence the name. It will decrease with increasing data redundancy,
obviously. The decrease will be proportional to the square root
of the redundancy if
I am aware of to opposing schools of thought about modelling residues
without density:
- You can argue that since you know those residues are present in the
sequence, you can model them, even though there is no or hardly any
density. If you do so, you must set the occupancy of those
I think if you cant see it dont build it, but deposit the data..
There are many (most?) structures with missing loops

Hello,
Thank you for the reply about the refmac 5.5.0066 error. I downloaded refmac
5.5.0068 but there appears to be a problem for ARPwARP to recognise the
version. I reinstalled ARPwARP and the install shell script freezes when it
looks for the refmac file.

When discussing this issue, perhaps we should not lose sight of
the fact that the statistics behind Rp.i.m. assume 'independent
observations'. Surely doing more than one rotation about the
same axis is likely to repeat the same systematic errors?

I think this approach (which Tim is not supporting) makes no sense.

Hello,
I would like to display thermal ellipsoids in pymol. What I did was using
rastep to make a r3d file and open it in pymol.
If I generate the r3d file with no extra options: rastep infile.pdb
outfile.r3d, pymol can open it.
But if I generate the file with rastep -auto -fancy1
These kind of problems with r3d can usually be traced back to the
header. In fact, the rastep page has the following snippet:
Describe the same ellipsoids colored by Biso, and create an input
module with no header records for inclusion in a composite image:
rastep -h -Bcolor 10. 30.
RE: Ian's and Eckhard's wise suggestion to deposit non-standard
parameters used to refine ligands:
I have had some ligands where the 1 8 peri-substituents (amino
methyl groups) on a 6/6 fused aromatic ring (deazapteridine derivatives)
were very clearly out of the plane. It took extensive
Interestingly, in the interactive 3D applet view of the ligand from the PDB
the two are perfectly in plane, whereas in the protein viewer the two groups
are clearly out of plane. I assume that this means that the coordinates for
the 3D ligand view are re-computed internally and are not
Hi,
If you have the latest version of pymol and ANISOU in your pdb file, you
just have to type:
