[PyMOL] nice DNA pdb and ring options

2009-02-23 Thread H. Adam Steinberg

I have three questions I'm hoping someone can help with.

1. Does anyone have, or can anyone point me to a program that will 
generate a nice pdb file that contains 50 or so base pairs of random 
sequence B form DNA with hydrogen bonds between the bases or no H bonds?


I need to be able to scultp the DNA and have one strand react to the 
pulling of the other strand. I also want to show the union of the AT and 
GC via H bonds. The H bonds can be regular bonds (and probably will have 
to be if I'm going to be sculpting). I can make the h bonds and make 
them real bonds for the sculpting, I'm just wondering of anyone has 
already done it or has a script around


2. When showing a cartoon of DNA the ribose ring in the backbone is 
always there no matter which setting you choose. How can I make the 
phosphates and the ribose rings show as a backbone cartoon tube and 
keep just the bases as filled sticks with rinngs?


3. Rings on DNA and RNA can be filled, in cartoon mode. But I can't get 
the rings to fill in on selected amino acids (H, W, Y, F) in a protein 
of that same file. Is there a fill amino acid ring setting?


Thanks in advance for anything you can offer,

Adam

Hello

You can look into 3DNA out of Rutgers
(http://rutchem.rutgers.edu/~xiangjun/3DNA/).  To make the image you
describe you will also need to use Raster3D.  3DNA has some basic
scripts for this but you will need to write your own to get the image
you describe.

[PyMOL] error with the APBS plugin

2009-02-23 Thread LOPES Anne

Hello,

I'm trying to use the APBS plugin to evaluate the electrostatic properties of 
my protein.
On the one hand, I've have this error: 
 
 Unable to assign parameters for the 1 atom in selection 'unassigned'. Please 
either remove
 thes unassigned atoms and re-start the calculation or fix their parameters in 
the generated PQR
 file and run the calculation using the modified PQR file (select 'Use another 
PQR' in 'Main')

I tried to remove the selection but it seems that the atom in the selection has 
not been
removed and I still obtain the same error message. 

Thus, I tried to edit the PQR file and I removed the atom in the PQR file but 
in this case I obtain
a new error message:

 Reading PQR-format atom data from /home/Models/pymol-generated.pqr.
 Vio_ctor2: some error occurred.
 Vio_ctor: Vio_ctor2() failed.
 Problem opening virtual socket /home/Models/pymol-generated.pqr!
 Error reading molecules!
 ObjectMapLoadDXFile-Error: Unable to open file!

could you explain the problem to me?
thank you for your help,

best regards,

Anne L





[PyMOL] Second CCP4 workshop in USA, 1st announcement

2009-02-23 Thread Sanishvili, Ruslan
We are pleased to announce that encouraged by last year's success we are
again organizing CCP4 workshop at Advanced Photon Source (APS), Argonne
National Laboratory (ANL). All details can be found here
http://www.ccp4.ac.uk/schools/APS-2009/

 

 

Title CCP4 school: From data collection to structure refinement and
beyond

Dates June 24 to July2

Site Advanced Photon Source, Argonne National Laboratory, Argonne,
Illinois (Near Chicago), USA

 

First time this year 

There will be two days of beamtime available at GM/CA-CAT beamlines
23ID-B and 23ID-D for collecting data from participants' samples.

 

The workshop content

The workshop will feature authors and experts of many modern
crystallographic software packages. It will be organized in three
sections: lectures, tutorials and hands-on trouble-shooting.

Note: There will be model data sets available for tutorials but data,
provided by participants, will have higher priority for the hands-on
sessions. Therefore, participants are encouraged to bring their problem
data sets and/or crystals.

 

Applicants

Graduate students, postdoctoral researchers and young scientists are
encouraged to apply. Only 20 applicants will be selected for
participation. Participants of the workshop are strongly encouraged to
bring their own problem data sets or crystals so the problems can be
addressed during data collection workshop and/or hands-on sessions.

 

Application

Application deadline is April 15. Selected participants will be notified
no later than April 20. Application form, the program, contact info and
other details can be found at 

http://www.ccp4.ac.uk/schools/APS-2009/
