[PyMOL] saving images

2004-09-13 Thread Greg C
Hello all,
I'm having a problem saving the pymol output as an image. I'm working with asingle alpha helix (~25 residues) with the residues displayed as lines, the backbone as a ribbon, and one or more of the residues as spheres. When i go to save the image, the lines are no longerpresent in the image, but still there in the pymol window. I should also note it's not a consistent problem. This happens about 60% of the time i try to save these images.Sometimes if i re-savethe picture, it works. 
ANy ideas?Thanks-GC

[PyMOL] saving images

2004-09-13 Thread Scott Classen

Hi Greg,
You might need to display your sidechains as sticks rather than lines 
in order for them to be visible when you write out your image file. Or 
perhaps, if you are not already doing it, you should raytrace your 
scene by hitting the ray button before you write out your image file.

[PyMOL] OS X Users: PyMOL 0.97 and APBS via fink - a success story!

2004-09-13 Thread Scott Classen

Hello PyMol and APBS communities,
I am here to report the successful compilation and installation of APBS 
on a Macintosh (Powerbook G4, OS X 10.3.5, XCode1.5, gcc 3.3 20030304 
(Apple Computer, Inc. build 1666),g77 3.4.1, and Python 2.3.3), and 
integration with PyMol via Michael Lerner's APBS plugin for PyMol. I 
thought I would just tell people of my experience and spread the good 
word that electrostatics are possible on a Mac.


I first installed the 0.97 version of PyMol via fink as per Bill 
Scott's instructions:



Hi Folks:

Thanks to the efforts of Jack Howarth, who has volunteered to maintain 
the pymol package in fink, we now have an up-to-date version 0.97 of 
the x-windows pymol in the 10.3 unstable branch of fink (or will as 
soon as cvs updates it -- usually within 24 hours or fewer).


If you don't have the unstable branch activated, the easiest way to 
install this is to do the following:


sudo mkdir -p /sw/fink/dists/local/main/finkinfo

sudo ln -s /sw/fink/dists/unstable/main/finkinfo/sci/pymol.info  
/sw/fink/dists/local/main/finkinfo/pymol.info
sudo ln -s /sw/fink/dists/unstable/main/finkinfo/sci/pymol.patch  
/sw/fink/dists/local/main/finkinfo/pymol.patch


fink install pymol


I had some problems with this step because I had several versions of 
Python installed via fink. Although the actual version in my path was 
2.3.3 there must have been several librarys, etc that were lying around 
my /sw/ folder and these were being referenced during the pymol compile 
resulting in an unusable pymol binary. The solution was to completely 
uninstall all fink versions of Python and reinstall only python23.


I also had a previous version of pymol.info and pymol.patch (0.86 I 
think ) already in the unstable branch of /sw and when I did a 
selfupdate-cvs I don't think the newer 0.97 version of pymol.info and 
pymol.patch were being downloaded. I eventually had to delete the 0.86 
version of pymol.info and .patch and ran selfupdate-cvs again. Then I 
followed Bill Scott's directions above, and everything worked fine.


Thanks again to Bill Scott for the fink install scripts for maloc and 
APBS. I have been playing around with this on and off for a few months 
and although I have been able to compile and install maloc I was having 
problems with APBS.





Hi folks:

I was alerted to the fact that I made a mistake in my original fink 
install scripts for apbs and its dependency called maloc.  The 
corrected ones are here:


http://chemistry.ucsc.edu/%7Ewgscott/fink/info/apbs.info
http://chemistry.ucsc.edu/%7Ewgscott/fink/info/maloc.info

I can't put these into fink because apbs requires a password download 
(sorry) so you have to download these scripts manually and put them in 
/sw/fink/dists/local/main/finkinfo and download the source code for 
apbs and put it into /sw/src .




The only problem I had was that the name of the source file in Bill 
Scott's apbs.info file was apbs-0.3.1.tar.bz2 and the source file that 
I downloaded from the APBS site was apbs-0.3.1.tar.gz. So I changed the 
name in the apbs.info file and although fink complained about the 
checksum size I just told it to go ahead and compile anyways. 
Everything went smoothly.


Here's another Thank You to Bill Scott, Michael Lerner, Jack Howrath, 
and Warren Delano.


Scott

[PyMOL] ATI Mobility Radeon 9000 Problems (?)

2004-09-13 Thread Warren DeLano
PyMOL Users,

A major PyMOL sponsor is having problems with the Mobility Radeon 9000 chip
on their Dell laptops under Windows XP.  I am curious to know whether others
have seen or are encountering similar problems with this chipset.  The issue
is as follows:

When attempting to choose atoms using the mouse, either picking or
selecting, the system experiences a hard system freeze and total loss of
responsiveness, no blue-screen, no mouse movement, no nothing.  The only
recovery is a power-off system reboot.  

Has anyone else experienced this behavior on identical or related hardware?
And if so, has anyone found a solution? such as a particular driver upgrade
or downgrade?  Or on the contrary, are there plenty of people out there with
Radeon 9000-based PCs running PyMOL just fine?

Any information about experiences with Radeon 8500-to-9200-based cards under
Windows could be helpful.  However, please send feedback to me directly
mailto:war...@delsci.com in order to avoid unnecessary technical traffic on
the mailing list.  I will of course summarize once the situation becomes
clear.

Cheers,
Warren
