RE: [PyMOL] spheres in very large ppdb files

[DeLano, W. <wa...@su...>]

Ron,

	This appears to be a Windows specific problem.  I can view spheres with =
1bgy.pdb just fine under Linux (albeit 168 MB of RAM...), but it blows =
out on Windows.

However, if you lower the sphere_quality (which only affects OpenGL =
quality), it holds together:

load 1bgy.pdb
set sphere_quality=3D0
show sph
ray

My suspicion is that PyMOL is trying to allocate a larger block of RAM =
than Windows can give it in order to hold the sphere graphics =
primitives.

Cheers,
Warren

Subject: [PyMOL] spheres in very large ppdb files


I'm relatively new to PyMOL, and I've been repeatedly running into
a problem with the pdb files I use, namely that whenever I try to use =
the
show spheres command the program crashes.  The same scripts work for=20
smaller proteins, so I'm guessing I need to find some way to increase =
the=20
memory allocation for the image, or something of the sort.

Anyone have any ideas?

BTW, I'm using the win32 build and one of the files I'm having problems=20
with is 1BGY, (the cytochrome BC1 complex)

Thanks,
