For me,
color red, resn asp+glu
works.

What is the selection syntax to select all GLU and ASP residues within
an object?

Hi,
Seems to work fine for me. I'm using version 1.3, although I doubt that this
could be
a version compatibility problem.
Could you give more specifics on how it doesn't work for you (ASPs not
colored red
or GLUs not colored red, etc.) ? Note that the parenthesis around 'resn glu'
aren't
Hi Jason,
sorry for last message ..
To label a residue by an mdo command cmd.mdo(int frame, string command) I can
pass as command one among these strings:
1) 'label %s, %s %s' % (..)
works fine but prints a message (I don't want) to the output window
1+) 'label %s, %s %s, quiet=1' %
Hello,
If I use save myscene.obj and I was looking at the surface
representation of a molecule, does the file contains only the external
surface of the protein, or are the internal cavities also included?
Thanks,

Dear all
thanks for the feedback. Indeed, after thinking for a second its totally
clear why 'select identifyer, (resn asp and resn glu)' returns { }.
So, speaking of syntax, '+' is OR and '' is AND?
Thanks again

Hi Ian,
You can try to set hash_max (set hash_max,200) to put a limit on memory
usage. Then again, an immediate crash can also mean the scene just isn't
going to fit in memory. Complex scenes I usually write in parts to povray
format, which I then combine and raytrace with povray.
Hope it helps,

I believe the confusion is caused by the simplified selection expression
in PyMOL (and some other visualization tools as well). I remember that
one of my colleagues once questioned strongly the reason of using OR
instead of AND in such situation.
The expression:
select resn GLU or resn ASP
I'm looking for a quick way to color two superimposed structures such that SSEs

Hi Martin,
You're in the wrong thread! In addition, + is not OR. OR merges expressions,
+ 'merges' identifiers in an expression. Further, in the code you gave it
said 'or'. It seems from this post you wrote 'and' in your script,
signifying a mismatch between what you were doing and what you
Hi, I have couple of questions for you, which could be very silly.
I downloaded the movie.py from http://www.rubor.de/, which is rTools 0.7.2 and
put it to the right directory. When I did run movie.py, nothing seemed wrong.
And then I did mv_clear, and still good. But when I do like : mv_move
Hey :)
It's good to note that programs are written by programmers, using
programmer's logic.The confusion is not so much caused by the
simplified expression, but by users with little background in
mathematics/logic assessing 'and' and 'or' from a linguistic
background. In computer science and

First of all, I was not complaining about the logic of the PyMOL
programmers. I tried to help find out the reason that might cause

yeah, its true.
We should work out a tutorial for this kind of things. Something where
there is only one line of instruction and one line of command, like:
1) Download a file
fetch pdb1.pdb
2) Select all ASP or GLU residues:
select acids, resn ASP+GLU
3) Suggestions?

Hi Johannes,
Coincidentally, I found myself in need of the same functionality the
other day. I came up with this:
from pymol import cmd
def clipped_by(at,v):
x,y,z = at.coord
nz = v[2]*(x-v[12])+v[5]*(y-v[13])+v[8]*(z-v[14])-v[11]
return nz v[15] and nz v[16]
def
Hi Johannes,
My guess is that you missed that get_view[0:8] is a _column-major_
rotation matrix. Transpose it before using it.
I decided to take a look at this problem for preparation of better
clipping planes in PyMOL. I got it to work in PyMOL using Python,
after much fussing about.
