Re: [PyMOL] maximum sphere-quality ?

[Xiao-Ping Z. <xp...@uc...>]

Dear Jason,

Thank you for your reply. I tried sphere_mode command on two machines. 

On Fedora 13, PyMol 1.3

set sphere_mode, 5  
disabled sphere display.
set sphere_mode, 4, 3, or 2 can show sphere, but it looks terrible. 

One Fedora 8, PyMol 1.3
set sphere_mode, 5
also disabled sphere display. But 4 gives a beautiful sphere view.

It seems that I need to fix OpenGL on Fedora 13. 

Best regards,

Xiao-Ping

When I tried to use the same command, PyMol crashed. The default sphere+AF8-quality is 1, 3 is the maximum value that I can use. I am curious what is the maximum value. I am running PyMol 1.3 on Fedora 13.
