Hi,

I download the following version.
And setup it.

My os is fedora core3 .

http://delsci.com/beta/
PyMOL 0.98beta05

Linux: pymol-0_98beta05-bin-linux-x86.tgz ~10 MB

But, when I run pymol, error occurs

How can I run it successfully?

This probably means that Tcl wasn't installed properly.

Subject: [PyMOL] Perspective Rendering (at last!)

PyMOL Users,

Hooray -- PyMOL's ray tracer can finally do perspective rendering!  Why is
this such a good thing?  

Because (1) ray-traced images are now always "what you see is what you get"
(WYSIWYG) versus OpenGL, (2) you can make rendered movies where molecules
move around still look right, and (3) it will soon become possible to
generate rendered stereo pairs with 'perfect' visual geometry (no more +/- 3
degree nonsense)...

However, there is a price to pay:  Even though I've beat on the code with
Apple's CHUD performance tool, perspective rendering is still 2-5X slower
than orthoscopic rendering.  That's because there are all kinds of
mathematical simplifications one can make in orthoscopic scenes (where all
the rays are parallel) that just don't apply to perspective scenes (where
all the rays aren't parallel).  Regardless, even with perspective turned on,
PyMOL's renderer is as fast as PovRay for most basic molecular scenes.

Updated beta builds for Windows & Mac at:  http://delsci.com/beta
http://delsci.com/macbeta

NOTE: perspective rendering is now the default in order to exactly match
OpenGL geometry.  This means that default rendering will seem noticably
slower.  If you want faster performance, then turn perspective off using
"set orthoscopic" before rendering.

Cheers,
Warren

Subject: [PyMOL] blinking pictures on sgi4DIRIX646

Hi, I have pymol 0.97 installed on a sgi workstation. However it keeps 
the old picture when I move the molecule, which seems like a long time 
delay. I wonder if people have similar experience.

Eric
