I invoke the raytracer by typing ray. I assume this is the internal raytracer. Does the raytracing-demo from the demo-menu work? The ray tracing demo works. But after running the raytracing-demo, pymol will crash if I type either: hide spheres show sticks ray or: hide spheres show lines ray Thanks, Morri thanks, Michael --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

RE: [PyMOL] Ray Tracing Crash
Morri, The RH9 Patch is described and published on: https://rhn.redhat.com/errata/RHBA-2003-136.html I would not expect Debian to suffer from the same crash. If it does, then we may be dealing with a genuine bug in PyMOL (assuming that you're not simply running out of RAM). With respect to Debian, in order to debug the problem, you might want to send me a PyMOL session file which crashes on your system when the next command issued is ray.

DeLano; 'Matt Franklin'; 'Morri Feldman' Cc: 'pymol-users' Subject: RE: [PyMOL] Ray Tracing Crash Warren and Matt, Thanks so much for your help. I must be using the stock glibc because set max_threads, 1 allows me to ray trace without crashing. I will tell my system administrator to patch glibc. Do you know where I should look for the patch? My debian/testing system at home also has trouble ray tracing especially sticks. When it fails I get a segmentation fault. Is my problem at home also due to an unpatched glibc? The error message is: /usr/bin/pymol: line 7: 32460 Segmentation fault python /usr/lib/python2.3/site-packages/pymol/__init__.py $* Thanks for creating such a great program, Morri --- Warren L.

This sounds to me like a potential threading deadlock, possible due to the broken threading in RedHat 9. Are you using the stock version or have you patched glibc? If you haven't patched your RedHat 9, then one way to be sure this is the problem is to set max_threads, 1 before issuing the ray command. If PyMOL doesn't hang, then you've found the culprit.

Sorry Thanks, Morri Morri Feldman Hi Morri - The progress bar for raytracing doesn't move linearly - the first half of the bar is covered fairly quickly, then more slowly, then very slowly, then the last fifth is usually covered in one jump. Are you sure you just aren't being impatient? Try raytracing a very simple scene, like a single amino acid in spheres mode, to see if it hangs then. Also try raytracing parts of your scene in case some funny bit of your molecule is causing this problem. Finally, try reducing the complexity of your surfaces and/or spheres: set surface_quality, -1 (0 is the default). Feel free to contact me directly - I'm local!

Perhaps it suffers from a different bug, but the one described earlier should be fixed by now, if it ever pertained to Debian.
