<div class="gmail_quote">Hello,<br>
<br>I am trying to determine the precise energies of a particular protein docking configuration. I have used the docking program FlexX to determine a potential binding mode. However, I am also trying to use AutoDock, and I am having a problem running AutoDockTools. Although the problem is not directly related to GROMACS, I was unable to get any help from the AutoDock mailing list.<br>
<br>
I have two Linux
machines, and both have AutoDockTools installed; on one machine ADT runs fine, but on the other, I receive the
following message after trying to launch ADT from the command line:<br>
<br>
================================================================<br>
$ adt<br>
setting PYTHONHOME environment<br>
Run AutoDockTools from /usr/local/MGLTools-1.5.6/MGLToolsPckgs/AutoDockTools<br>
libGL warning: 3D driver claims to not support visual 0x4b<br>
could not import _glextlib<br>
Segmentation fault<br>
$<br>
================================================================<br>
<br>
The ADT splash screen appears for a few seconds, but closes at ~3% loading.<br>
<br>
I tried increasing the stacksize with "limit stacksize unlimited", but that does not seem to help.<br>
<br>
My computer is running Red Hat Enterprise Linux. It does not
have a discrete graphics card, but the graphics controller is the Intel
82845G/GL Integrated Graphics Device; the OpenGL renderer is "Mesa DRI
Intel(R) 845G 20061017 x86/MMX/SSE2".<br>
<br>
Running glxgears -info gives the following information (and numerous GL extensions):<br>
<br>
===============================================================<br>
$ glxgears -info<br>
<br>
libGL warning: 3D driver claims to not support visual 0x4b<br>
GL_RENDERER = Mesa DRI Intel(R) 845G 20061017 x86/MMX/SSE2<br>
GL_VERSION = 1.3 Mesa 6.5.1<br>
GL_VENDOR = Tungsten Graphics, Inc<br>
===============================================================<br>
<br>
My other computer has an ATI Mobility Radeon 7500 graphics processor, and
AutoDockTools runs fine on it (though there are other differences
between both computers). Note that I do not have a proprietary ATI graphics
driver on the other computer (as I could not find one on the ATI website), and
I am just using Mesa drivers (and it gives the same libGL warning).<br><br>I am not sure where the "Segmentation Fault" comes from (or what it means in this case).<br>
<br>
Please advise,<br>
