hi folks, anyone know if the volume plane tool will support arbitrary orientation of the plane any time soon? -Jeff

Silhouette edges around dashed wire-style bonds
by Dipl.-Ing. Thomas Mitterfellner 05 Jan '11

05 Jan '11

Hello! In some of my structures, I need dashed bonds to indicate hydrogen bonding or metal complexation. As I understand it, in order for bonds to be displayed as dashed, they need to be wire-style. I wondered if silhouette edges could also be extended to these wire-style bonds? Alternatively, could stick-style bonds possibly be displayed in a dashed fashion? Maybe as a series of cylinders, each separated by a certain distance, or eg. as a series of equally spaced small spheres. Thank you, Thomas

Re: [Chimera-users] How are chains paired in morphing?

The sequences are in input order unless you ask for the return value to be a dictionary (with the 'asDict' keyword). --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Feb 22, 2010, at 11:25 AM, Conrad Huang wrote: > There's a comment in Segment.py: > > # Get the chains from each model.

saving moved maps
by Erika Mancini 26 Feb '10

Dear Chimera users, is it possible, after moving maps around, to save them into their new positions? I tried save map from volume viewer, but maps are saved in their original positions. Thanks! erika

question
by Huang, Xinlei 25 Feb '10

25 Feb '10

Hi, Thank you for inventing the software, it rocks! By the way I have a question about viewing the 3D reconstruction image of a Virus like particle containing small nanoparticle cores. When I tried to increase the electron density in order to see the inside cores there always was a box showed up along with the nanoparticle. I want to know is there a way to remove the outside box? Here I attach an image to explain better what I mean. I appreciate you help. Thanks xinlei

variable surface visualization
by Zambonelli, Carlo 25 Feb '10

25 Feb '10

Dear All, I am working with a glycoprotein structure and I want to visualize the protein surface as a continuum with the glycans sticking out as sticks. If I visualize the surface of the whole molecule (including sugars), and then I select the sugars only and visualize them as sticks, the surface of the amino acids immediately connected to the sugar (Asn) appear to be clipped. One solution could be to the following: 1. save the model with a different name 2. load the 2 identical structures and align them 3. remove the sugars from one structure only and use it to visualize the protein 4. the second structure is used for visualizing the sugars and not the protein. I used to do something similar with Pymol, and it should work with Chimera as well, but I am sure there is a better/simpler solution. Any suggestion? Thank you for your help. Carlo

I think you just want to take whatever commands you were using in IDLE and put them in a Python script (file ending: .py). You can then execute them with "chimera --nogui myscript.py". If you need to supply arguments to the script then instead run it like this: "chimera --nogui --script myscript.py -- arg1 arg2 ...". This is described here: http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/options.html --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu

Hi everybody, I don`t find a link on your homepage to download the chimera version 1.3. I only find version before or after chimera 1.3. How can I download the version 1.3? I need this version for my studies. Thank you, Nicole Heute schon ge"freeMail"t? Jetzt kostenlose E-Mail-Adresse sichern! http://email.freenet.de/dienste/emailoffice/produktuebersicht/basic/mail/in…

To summarize, if Chimera is installed as /Applications/Chimera , to start it from Terminal you would type: /Applications/Chimera.app/Contents/MacOS/chimera (or if it is in a different place or you gave it a different name, substitute those instead). Since that is kind of a long thing to type, you may want to make an alias. My aliases are in the file named .tcshrc in my home directory on the mac, but the filename could be different depending on what shell you are using (maybe .bashrc or .cshrc or something like that). I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco
