Chimera Settings
by Nuwan De Silva 24 Apr '19

24 Apr '19

Hi, Every time when when I open a file my background color, and presets, changes. I want to keep them same for every time. How can I set these things? For example, I wanted to have A) Presets —> Select Publication 1 B) Tools —> Structure —> Find H bonds C) Actions —> Atoms & Bonds —> Balls & Sticks Thank you, Nuwan

about select and label a residul with another different from the color of the whole model
by 张雷 13 Apr '19

13 Apr '19

Hi the experts of Chimera, Good noon! I had selected a residul and labeled it with the commands sel #0:500 rlabel #0:500. Then, the label can be displayed on the selected residul. How could I change the color of the label and display the label in a different color different from the color of the whole model? Thank a lot! Sincerely, Lei Zhang Peking University, Beijing, China

Hidden water molecules
by Michael Sharkey 11 Apr '19

11 Apr '19

Hi I'm trying to visualise water molecules associated with the crystal structure of an enzyme (specifically PDB ID: 1C1D). They're listed when I open the pdb as a text file using WordPad, but I can't for the life of me get them to appear on the screen when I try to visualise the structure in Chimera (v. 1.10.2). What am I missing? Thanks in advance Mike --

Constrainted fitting
by Christoph Wigge 22 Mar '19

22 Mar '19

Dear all, I would like to fit two protein monomers that form a dimer into an em density map. I know from previous mutagenesis studies that the binding takes place with two tryptophan residues and the counterpart binding pocket. How can I set this interaction as fixed so that chimera fits the rest of the molecule according to the density map without continuously changing this part of the essential protein protein interaction? I would like to fit that interaction manually and then exclude it from the automatic procedure. Thank you very much in advance. Bests Christoph Wigge

rmsd graph
by SEFA ÇELİK 31 Jan '19

31 Jan '19

Dear Dr. I am using Chimera software(windows platform). I tried to get rmsd graph(using the plotting in the MD Movie trajectory viewer). And I got the result. But, graph's x-axis "frame" and y-axis "rmsd" value. I want the x axis to be the "time". Briefly, I want to see how the value of rmsd changes with time. *I added files to the e-mail. Can you explain what "1001 frames" mean? And how do I convert "1001 frames" to time. I want to see the RMSD change by time.* Can you help with this? Could you explain in detail? Best regard Assoc Prof. Dr. Sefa Celik

FW: Chimera [viewer] for iOS in the future?
by Williams, Joanne 05 Nov '18

05 Nov '18

From: Bryan Crawford <bryanc(a)unb.ca> Date: Wednesday, October 31, 2018 at 3:53 PM To: "chimera(a)cgl.ucsf.edu" <chimera(a)cgl.ucsf.edu> Subject: Chimera [viewer] for iOS in the future? Hello, I use Chimera occasionally in my research, and extensively for teaching (biochemistry, cell biology, developmental biology). It is now the only remaining piece of software I use that requires me to bring a laptop computer to class. For everything else (PDFs, animations, Keynote presentations, etc.) I can use my iPad which connects by AirPlay to the projector, and screencast everything using Doceri. Furthermore, the touch-screen interface of the iPad seems ideally suited for many of the analyses and/or molecular renderings people use Chimera for. So I’m wondering if there are any plans to produce either a full or partial version (perhaps with only viewing capabilities) of Chimera that runs on iOS? If there is, I would be very happy to help with beta testing. If not, can I ask if you can recommend any software that runs on iOS that I might consider? Cheers -- Dr. B.D.Crawford Professor Matrix Dynamics Lab Department of Biology University of New Brunswick Fredericton, NB, Canada

Batch Processing of Molecular Attributes
by Benjamin Feinsilver 01 Nov '18

01 Nov '18

Hello, Is it possible to pass a CSV file to Chimera containing a list of SMILEs, then output their molecular attributes in a new CSV file? For example, volume, surface area, the number of surface points with positive electrostatic potential, and the energy of the molecule's current 3D conformation. If so, would you please let me know how I would accomplish this? Thanks, Ben

Chimera use
by Hui Min 31 Oct '18

31 Oct '18

Hi there, Sorry to disturb you. I have a question of how to use the Chimera software. If I've already got a .pdb file and use SMART to predict the domains, how can I mark the 3D structure with user defined color？ Thank you in advance for your help -- *Hui Min* Postdoctoral Scholar Research, Department of Internal Medicine, College of Medicine, University of South Florida, Tampa, FL 33612 minh8(a)health.usf.edu

How can I load a list of residues of protein?
by Paris Tzou 31 Oct '18

31 Oct '18

Dear all, I want to load a file containing a lit of residues of protein which is already shown in Chimera. I don't want to manually select the residues under investigation through "Favorite -- Sequence". Is there a way of doing this ? I know I can do it using command line like:select #0:15-17.C,263-265, 300-310.A. Instead, I can have a text file with content like: 15,C 16,C 17,C 263,A 264,A 265,A Thank you very much. Paris Tzou
