Re: [PyMOL] Selecting ASP and GLU
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 needed.

Re: [PyMOL] Selecting ASP and GLU
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 actually means select (resn == GLU) or (resn == ASP) The reason of using Boolean operator *or* is very clean when the two operands are stated completely. But when the operands are simplified, our first reaction is to use *and* because it is very natural to say I want GLU *and* ASP if you want both GLU and ASP. And it is even more confusing in Jmol : select 110 or 112 (select resno==110 or resn==112) if want you really want is 110 *and* 112 :) hongbo On 03/01/2011 05:43 PM, Jason Vertrees wrote: Hi Martin, To select all ASPs and GLUs just type, select resn GLU+ASP or select resn GLU or resn ASP or, if you need parentheses, select ((resn GLU) or (resn ASP)) Maybe this will help: # fetch a test protein fetch 1rsy, async=0 # color all ASPs and GLUs red color tv_red, (resn ASP or resn GLU) While the boolean 'and' works, the following will fail to select and color any atoms: color tv_red, (resn ASP and resn GLU) because there will be no _single atom_ in both an ASP and a GLU.

Re: [PyMOL] Selecting ASP and GLU
Hi Martin - ** Short answer: Use `resn asp+glu` (although your original command actually works for me). ** Not-so-short answer, with a bonus question about comment syntax: The Asp/Glu line of your script can be condensed slightly using a plus sign, but the original syntax of that line actually works fine for me (PyMOL v.1.3, Fink/X11 build on Mac OS 10.6.6). However, for me, the lines to remove waters and add hydrogens fail. To elaborate, I've found that, with certain commands (but oddly not all of them -- for example, the `color` statements in your original script handle this just fine), adding a comment on the same line returns a Malformed selection error. I don't know if this is by design or an unintended feature. I would expect these comments to be handled the same way as in Python code, but for whatever reason, they are not. (Query for the developers: Is there a specific reason some PyMOL functions attempt to include the hash mark and comment in the selection, rather than ignoring everything after the #? Perhaps it has something to do with the number of arguments--both the commands below that fail with an inline comment take only a single selection argument.) If you really want to keep the comment on the same line, add a semicolon between the command and the comment. The other option, of course, is to place the comment on the previous line. Also, you can use `remove solvent` to cover all the different ways of describing water (HOH, WAT, H2O). Try this: # remove water remove solvent; # or put the comment on the same line after a semicolon # add hydrogens h_add; # this one also requires a semicolon # basic view as surface color grey90 # color lys blue, cys yellow, asp/glu red color slate, resn lys# comments here seem to work without the semicolon color paleyellow, resn cys color tv_red, resn asp+glu Hope that helps, -- Jared Sampson Xiangpeng Kong Lab NYU Langone Medical Center New York, NY 10016 212-263-7898 On Mar 1, 2011, at 7:44 AM, Martin Hediger wrote: Dear all What is the selection syntax to select all GLU and ASP residues within an object?
