[ccp4bb] Coot 0.6: new binaries and NEW CITATION

2009-12-14 Thread Kevin Cowtan

Two things for Coot users...

Firstly, I have just uplaoded the remaining Linux binaries for Coot 0.6, 
 i.e. Fedora 8, Fedora 10 and Ubuntu 6.06 (with python and gtk2 gui). 
You can find them on the Coot website here: 
http://www.biop.ox.ac.uk/coot/software/binaries/releases/


Secondly, please could you stop citing the 2006 Coot paper from today!

Specifically, do not cite Emsley and Cowtan (2006) Acta Cryst D62
because by doing so you rob Bernhard Lohkamp and Bill Scott of the well
deserved credit for their work. Instead, could you cite the following paper:

  Emsley P, Lohkamp B, Scott W, Cowtan K (2010)
  Features and Development of Coot Acta Cryst D66 (in press)

Thanks!
Kevin


Re: [ccp4bb] Error in CAD during ARP/wWARP run in sharp/autoSHARP - also posted in sharp discuss

Well - cad cant work with that script so somehow it is being generated 
wrongly, presumanly in Arp/warp stage..




It would need input such as:
LABIN FILE 1 E1=FBshasol E2 = something - presumably SIGFBshasol

Re: [ccp4bb] MR question

2009-12-14 Thread Eleanor Dodson
The 2nd peak is a shoulder of the origin peak at 1.0 0 0  so should be 
ignored..


The 3rd peak is 16% of the origin - rather marginal I would say. So I 
dont think there is clear evidence of translational NCS

Morning all

Apologies for the simple question. I have a structure I would like to
solve using molecular replacement. I am a bit confused by the patterson
peaks. There appears to be a large non-origin peak (although it is
apparently symmetry-related to the origin?). Does this mean that there
is some translation occurring in the asymmetric unit? Or is there
non-crystallographic symmetry? Does anyone know what I should do to
address this? I have continued with the molecular replacement as normal
and did not get a solution with Phaser. Molrep gives a solution that
appears correct based on the maps and refines reasonably well.

[ccp4bb] question about refmac/coot findwater

2009-12-14 Thread Boaz Shaanan
Hi,

This question may have been asked before, so please excuse me for re-posting 
it. I notice that when I do a round of 10 cycles of refmac combined with 
(5cycles, 3 sigma level, 1.4 A resolution) of findwaters in coot, some water 
molecules from the different coot cycles fall one on top of the other. Does 
that mean that coot does not check for clashes between water molecules detected 
in previous cycles ? And in any case, does coot put another water molecule in 
the same place (or nearly) because there is still residual difference density 
after placing the first one ? I assume that this happens here, which in fact 
can be beneficial in my current structure where I'm also trying to locate  
chloride ions (I don't have anomalous data in the correct wavelength so I can't 
depend on that).

Please advise. Thanks.

[ccp4bb] 2010 Hybrid Methods Symposium Abstract Deadline Today

2009-12-14 Thread Wes Sundquist
Dear Colleagues:

This is a reminder that today is the deadline for Early Registration and 
Abstract Submission for the 2010 Symposium on Structural Analysis of 
Supramolecular Assemblies by Hybrid Methods. The Symposium will be held at 
Granlibakken Conference Center, Lake Tahoe, California, and the dates are March 
10-14, 2010. The overall goal of the Symposium is to illustrate the power of 
combining state of the art methods to tackle important and challenging 
biological problems and to identify limitations and gaps in currently practiced 
hybrid methods. We are fortunate to have recruited two outstanding Keynote 
Speakers: Stephen C. Harrison (Harvard) and Thomas D. Pollard (Yale), as well 
as a great program of platform speakers who utilize multiple approaches to 
investigate the structural biology of complex biological systems. Further 
details and registration information can be obtained at our website: 
http://www.hybridmethods2010.com/index.html. Note that a series of platform and 
workshop talks will also be selected from submitted abstracts, which will 
enable us to feature hot emerging topics and to provide qualified students and 
postdocs with the opportunity to present their work.

The Symposium builds on a series of very successful previous meetings on the 
same theme from 2004-2008. The central premise is that gaining a comprehensive 
understanding of the highly sophisticated machines, complexes, and organelles 
of the cell requires the coordinated application of a number of complementary 
biophysical approaches (hybrid methods). A new innovation at the 2010 meeting 
will be a special workshop on Harnessing Different Wavelengths of 
Electromagnetic Radiation, which will feature the rapidly developing fields of 
subdiffraction light microscopy and other emerging imaging techniques (e.g., 
X-ray tomography), as well as new advances within more traditional hybrid 
approaches such as the interfaces between electron microscopy, X-ray 
crystallography, and computational biology.  Featured topics will also include 
other biophysical methods, proteomics and cell biology.


The meeting will be divided into seven Scientific Sessions and one Special 
Methods Workshop

Session I: Hybrid Approaches to Macromolecular Filaments
Session II: Hybrid Approaches to Membrane Complexes
Session III: Hybrid Approaches to Dynamic Assemblies
Session IV: Computational Approaches to Hybrid Analyses
Session V: Hybrid Approaches to Global Analyses
Session VI: Hybrid Approaches to Cell Biology
Session VII: Hybrid Approaches to Nanomachines
Special Methods Workshop: Harnessing Different Wavelengths of Electromagnetic 
Radiation


We hope to see you there for four days of exciting science (as well as some 
outstanding skiing!).


Sincerely yours,

The Organizing Committee:

Wes Sundquist, Chair
Phoebe Stewart, Co-Chair
Dorit Hanein, Nobutaka Hirokawa, Felix Rey, Alasdair Steven, and Bill Weis.

[ccp4bb] When can I say the refinement is done?

[ccp4bb] CALL FOR ESRF SYNCHROTRON BEAM TIME WITH ONLINE MICOSPEC AT BEAMLINE ID14-2 (19th to 22nd of February 2010)

2009-12-14 Thread David FLOT

--
CALL FOR PROPOSALS FOR BEAMTIME WITH ONLINE MICROSPEC

*Proposal Deadline 13th of January 2010*

There will be beamtime available at the ESRF for MX data collection with 
a setup that allows online monitoring of UV/VIS spectral changes of the 
crystal during the X-ray diffraction experiment. Users who are 
interested in using this beam time (including those who are members of 
BAG Groups) should use the following mechanism:
http://www.esrf.fr/UsersAndScience/UserGuide/Applying/ProposalGuidelines/MXnon-BAGproposal 

and it must be clearly indicated in the title of the proposal form that 
the online monitoring of spectral changes is necessary for the project.


A brief description of the device is given below.  However, Users are 
encouraged to consult the web pages for detailed information:
http://www.esrf.fr/UsersAndScience/Experiments/MX/How_to_use_our_beamlines/Run_Your_Experiment/Microspectrophotometer_User_Guide 



As this is not a standard setup, it might take a significant amount of 
time to train users, align the device, and analyze the data in order to 
derive relevant data collection schemes. We will therefore schedule 24 
hours for each project.  The deadline for this specific application is 
13th of January 2010.


It is strongly recommended to record beforehand an absorption 
(fluorescence) spectrum of the crystal on a home microspectrophotometer 
such as the 4dx one, or at an off-line facility such as the ESRF 
Cryobench, and to provide it in the application form. Such a spectrum 
would greatly help to determine the feasibility of the experiment. For 
optimal experimental conditions, crystals should be frozen in minimal 
amounts of cryosolution, especially when the crystals are small. 
Finally, please note that the ESRF sample changer cannot be operated at 
the same time as the on-line microspec.



*Dates of beam-time: 19th to 22nd of February 2010
*Storage Uniform Filling (200mA)
Beamline: ID14-2
Energy: 13.29 keV

Specifications:
UV/VIS-range: 250 - 1100 nm

[ccp4bb] announcement EMBO Practical Course : Scientific Programming and Data Visualisation for Structural Biology

2009-12-14 Thread Panne Daniel
Course Announcement 


EMBO Practical Course : Scientific Programming and Data Visualisation 
for Structural Biology
 
We are pleased to announce our practical course  Scientific Programming and 
Data Visualisation for Structural Biology  offered at the newly constructed 
Advanced Training Center, EMBL, Heidelberg, Germany from May 5-7, 2010. 

The course is designed primarily for structural biologists (scientists from 
other disciplines are welcomed to apply). The goals of the course is to allow 
students to learn and master computational skills that are frequently required 
in less routine projects, and to learn methods of data visualization. Lecture 
sessions will cover data animation, Python programming for Molecular Dynamics 
and Drug Design, GUI development and high performance computing as well as 
modern programming tools on OSX.

Three (3) parallel tutorial tracks will be offered (you can only select one):
Molecular Visualization with Maya.
Scientific Programming with Python,
OS X Programming.
As part of this course each participant will initiate a project relevant to 
their own research area, using the newly acquired skills. Attendees are also 
invited to present a poster (describing their research), that would benefit 
from molecular visualization or new software tools. There are several 
fellowships available!

Deadline to submit your application is January 17, 2010, Register Today.

Tutorial Lecturers:
Alex Griekspor - Developer of the Papers
Gaël McGill - Expert in Molecular Movies and Animation - to view examples of 
his work visit MolecularMovies.org.
Ian Stokes-Rees - Harvard University Python programmer, with extensive 
experience in teaching.
Joint lectures will be presented by expert programmers with extensive 
experience in structural biology and computational approaches:
Kathryn Loving - Scientist from Schrodinger, will discuss utilizing Python in 
docking and macromolecular simulations.
Bernhard Lohkamp - Karolinska Institute, will discuss designing graphical user 
interfaces with Python.

For additional information please visit the course website.

Comments from previous participants:
Fantastic workshop. Getting software developers and experimental biologists to 
talk the same language is essential.;
The OS X course was informative and very interesting. Until this class I did 
not know anything about all the excellent developer tools available for writing 
OS X programs, and I had no idea that OS X programming would be this 
approachable for novices.
[...] the Python tutorial was understandably constrained in terms of its 
depth. However, I think maintaining a focus on the fundamentals [...] will 
provide a useful foundation for those who want to apply the skills on their 
own.
Gaël McGill gave a brilliant [molecular animation] presentation and tutorial.

Please feel free to  e-mail Piotrek Sliz or Daniel Panne, if you have any 
questions.

I have a 10-residue stretch of a protein that adopts an interesting  
conformation; I'd like to know if this conformation occurs in other  
proteins. I'd welcome suggestions for tools that will allow me to to  
search for this peptide conformation in the PDB.


I naturally thought of DALI, but it seems to require a minimum length  
of 30 residues.

I believe that Coot also outputs R 3 2 :H (Paul can clarify).

/start minor rant
We need some standardization on the hexagonal setting for R32.  Having
just suffered through a fairly brutal structure determination in this
space group, I can say that there are some 'issues' with this.  For
instance HKL outputs a line with the spacegroup set as R32 but the cell
axes being for the hexagonal setting.  If you import this into CCP4, it
is not detected as H32, rather, it stays as R32 and problems ensue.  So
based on my recent experience, there are apparently three, not mutually
acceptable, ways to denote the hexagonal setting of R32:

R32
H32
R32 :H

Can't we all just get along?

Hello,

I think you can you  SSM
Secondary Structure Matching
at PDBe

http://www.ebi.ac.uk/msd-srv/ssm/

you can upload your coordinate file
and try to match to the whole of PDB.

Hope it helps

I naturally thought of DALI, but it seems to require a minimum length of 30

Re: [ccp4bb] H32 or R 3 2 :H

2009-12-14 Thread Peter Zwart
Hi Stephen,

 R32
 H32
 R32 :H

Correct. These are all hexagonal setting. As far as I know, the
hexagonal setting of R32 (R32:H) is the first one that comes up in the
ITvA as is listed a R32. The rhombohedral/primitive setting of R32
(R32:R) comes second in the ITvA, I guess the first setting takes
precedence. H32 is a pdb/ccp4ism.

In my cctbx-skewed view, it looks like this:

R32 ==  R32:H (== H32; not supported by the cctbx)

R32:R is the primitive setting of R32:H

Appending the setting to the space group makes life easier (no
ambiguities) and you can do more funky stuff if one has the
stomach/need to do so [like  P212121 (a+b,a-b,c) ].

2009-12-14 Thread Soisson, Stephen M
Thanks Peter.  The unfortunate thing is that not all of the programs are
able to understand these different notations, and that they
preferentially use different ones.  It would be nice if we all agreed to
standardize.  I, personally, have no problem with R 3 2 :H since that is
what it really is.

[ccp4bb] configuration or install issue with tk

2009-12-14 Thread Stuart Endostreeter
 Fellow users,

 I just installed v6.1.2 on Ubuntu 9.0.4 today and have run into the
following problem when I try to run ccp4i for the first time as root to
configure the program:

 r...@:/home//Documents# ccp4i
 No protocol specified
 Application initialization failed: couldn't connect to display :0.0
 Error in startup script: can't read tk_version: no such variable
 ��� while executing
 catch set system(TK_VERSION) $tk_version
 ��� (file /usr/local/ccp4/ccp4-6.1.2/ccp4i/bin/ccp4i.tcl line 1)
 ��� (file /usr/local/ccp4/ccp4-6.1.2//bin/ccp4i line 1)

 The odd thing is that I can launch ccp4i just fine as a regular user, but
then of course I get the message about the first time ccp4i has been run
and the need to configure it, which requires administrator level access.

 Anyone have any ideas?

 Thanks,
 Stuart Endo-Streeter
 

Re: [ccp4bb] configuration or install issue with tk

2009-12-14 Thread Mark A. White
Stuart,

Are you logged-in as root or are you working in a root shell ( using su
or sudo)?  Depending on your security settings X-windows may not permit
a program that is run from a root shell to access the display, which
belongs to the user logged-in through X-windows.

I get around the administrator access issue by installing CCP4, and all
other non-OS software, with non-root ownership, a non-root administrator
account, which shares the environment with all other users.  For one
thing, I do not want to source the multitude of /etc/csh.cshrc
and .bashrc files as root.  I am sure that others have different, and
probably more elegant, solutions to this problem.

PS. It also seems that the TCL/TK environment is not set in the root
shell you are using.

Good luck,
Mark

With 'sudo' you should not have this issue.

I agree, though, that having a separate user account to install 
crystallographic programs is quite an advantage from an administrative

I was running from a root shell.  Ubuntu does not let me login as root.  That

last time I on a CentOS system I had to login as root.  I will try to reinstall

Another way around this (assuming you have ssh server running) is login
to a graphics desktop as yourself, then ssh r...@localhost
Depending how your SSH, SSHD are configured, you may have to ssh -X or
ssh -Y, but the X11 server will be available to the remote session
so you can run ccp4i (or nedit or xclock or whatever X application),
with copy and paste between the remote session window(s) and local, all

This is also great for setting up crystallography for a number of workstations-
install all the programs as a normal user on an nfs-mounted disk.
Now whoever mounts that disk can source your master setup file and run the 
programs.
Rather than installing as root in the usual /usr/local/bin/ or wherever,
on every workstation. The actual system disks then just contain the
operating system, which you can reinstall in a few hours (or less from an image)
if they become corrupted or need to be updated to the latest distro.

I don't think you need to reinstall- just open a terminal in your graphics 
desktop,
ssh -X r...@localhost, verify that $DISPLAY is set and xclock works, then source 
ccp4.setup and run ccp4i. (could be wrong about that, though)
