[ccp4bb] (Off-topic) X-mas gift idea for cool scientists?

2011-12-02 Thread Gerard DVD Kleywegt

Hi all,

Someone pointed me to this: 
http://cdn3.spiegel.de/images/image-287176-galleryV9-qokb.jpg


Apparently, it is a page from this book: 
http://www.amazon.co.uk/Science-Ink-Tattoos-Obsessed/dp/1402783604


Personally, if I had to get a tramp stamp, it would obviously be of 1cbs 
(http://pdbe.org/1cbs)

[ccp4bb] Script problem

2011-12-02 Thread Simon Kolstoe
Hi there,

I've got a text file with multiple conformations of a ligand that has been 
docked to a protein using autodock, which I am trying to split into separate 
pdb files in order to visualise in pymol/coot etc.

Previously I've used the script pasted below, but it is now falling over just 
after it creates the pdb file with the error:

expr: syntax error
csplit: }: bad repetition count
./split_results.com: line 11: syntax error near unexpected token `('
./split_results.com: line 11: `foreach f ($outputname.[0-9][0-9][0-9])'

Can any of you wizzy programmers give me a hand with getting this to work 
again? (it's on a mac just in the normal terminal)

Thanks,

Simon

The script:

#!
grep '^DOCKED' output.dlg | cut -c9- > my_docking.pdbqt
cut -c-66 my_docking.pdbqt > my_docking.pdb
# csh to split pdb files from autodock output.
# edit outputname.
#
set outputname=output
set a=`grep ENDMDL my_docking.pdb | wc -l`
set b=`expr $a - 2`
csplit -k -s -n 3 -f $outputname. my_docking.pdb '/^ENDMDL/+1' '{'$b'}'
foreach f ($outputname.[0-9][0-9][0-9])
mv $f $f.pdb
end

This appears to be a csh or tcsh script: if so the first line must be
"#!/bin/csh" or "#!/bin/tcsh", otherwise it takes it to be a sh
script.

Cheers

This doesn't answer your question.

But I'd just do it in Coot:

(define (split-multi-alt-confs)
  (using-active-atom
  (let ((alt-confs (residue-alt-confs aa-imol aa-chain-id aa-res-no 
aa-ins-code)))

(for-each (lambda (alt-conf)
(let* ((ss (string-append "//*/*/*: ," alt-conf ""))
   (imol-new (new-molecule-by-atom-selection aa-imol ss))
   (new-name (string-append (strip-extension (molecule-name 
aa-imol))

"-alt-conf-" alt-conf)))
  (set-molecule-name imol-new new-name)))
  (residue-alt-confs aa-imol aa-chain-id aa-res-no aa-ins-code)


Centre on your interesting ligand with multiple alt-confs and then use 
scripting -> scheme


(split-multi-alt-confs)

If you want to write out the various pdb files, you can add in a
(write-pdb-file imol-new (string-append (molecule-name imol-new) ".pdb"))
before the set-molecule-name... line.

[ccp4bb] Diffraction Data Deposition -> Data Woes in general

2011-12-02 Thread Sheriff, Steven
All:

The recent discussion on the CCP4BB about Diffraction Data Deposition made me 
think at that at least certain people might be interested in an article in 
Thursday, Dec. 1, New York Times business section entitled "A Genome Deluge" in 
the print version:

http://www.nytimes.com/2011/12/01/business/dna-sequencing-caught-in-deluge-of-data.html?_r=1&scp=1&sq=Genome%20Deluge&st=Search

It makes the woes of crystallography data seem tame by comparison.

[ccp4bb] refmac model statistics in cif format

2011-12-02 Thread wtempel
Hello all.
Did anyone encounter the following?
Running refmac 5.6.0117/ccp4-6.2/ccp4i-2.1.0, I hoped to obtain, for
pdb_extract, the appropriate output model statistics. When I did not
find the cif file with a modification date similar to my output
coordinates, I noticed a series of
${project}_${crystalname}_${jobnumber}_${dataset}.refmac.cif files,
with appropriate job numbers, but with identical older creation dates.
They all have the same sizes, and random checksum comparison indicates
that they are in fact identical, corresponding to the oldest refmac
job in the group. This does not happen all the time (with other
projects) under this software configuration. Any ideas out there what
might be going on?
Thank you,
Wolfram Tempel


[ccp4bb] Software for optimizing drug molecules

2011-12-02 Thread jie liu
Dear All

I have a protein crystal structure with a bonded drug molecule. Before I 
proceed to serious and expensive computational approach, is there a free and 
simple software that I can use to do a little optimization of  the drug in 
order to enhance the bonding affinity, solubility and so on? I would like to 
have a general idea before going further.

Any input will be greatly appreciated. Have a good weekend!

[ccp4bb] Postdoctoral applications JAEdoc-CSIC in Structural biology of viral fibres

2011-12-02 Thread Mark J van Raaij
Our research group is looking for applicants with a Ph.D. degree to apply for a 
3 year postdoctoral position supported by the CSIC JAEdoc program. The deadline 
for these applications is January 13th, 2012. Information, in Spanish, about 
this postdoctoral program can be found at the CSIC web page: 
https://sede.csic.gob.es/servicios/formacion-y-empleo/convocatorias-personal/-/convocatoria/34736
Our main line of research is Structual Biology of Viral Fibres. We use X-ray 
crystallography to solve fibre structures and aim to use the structural 
knowledge in applications. Proposals focussing on bacteriophage fibres or on 
adenovirus fibres are envisaged.

We are looking for postdoctoral fellows with experience in one or more of the 
following techniques and willingness to learn the others. 
- construction of bacterial expression vectors
- protein purification
- protein crystallography
- biology of bacteriophages or adenovirus
Useful language skills include Unix and English.

Recent publications of our lab include:
- Bartual SG, Otero JM, Garcia-Doval C, Llamas-Saiz AL, Kahn R, Fox GC, van 
Raaij MJ. Structure of the bacteriophage T4 long tail fiber receptor-binding 
tip. Proc Natl Acad Sci USA. 2010 Nov 23;107(47):20287-92.
- Guardado-Calvo P, Muñoz EM, Llamas-Saiz AL, Fox GC, Kahn R, Curiel DT, 
Glasgow JN, van Raaij MJ. Crystallographic structure of porcine adenovirus type 
4 fiber head and galectin domains. J Virol. 2010 Oct;84(20):10558-68.

If selected, positions will be available before summer 2012.

[ccp4bb] Software for showing crystal packing

2011-12-02 Thread Yuri Pompeu
Hello everyone,
Whats a "good" software for showing crystal packing and unit cell, axes , etc...
I know pymol and coot will do it but would love to hear other 
possibilities/ideas.
Cheers,

Swiss PDB viewer will do this. Also XPAND will fill a unit cell with a
symmetry generated PDB.
