Chimera for MOFs
by Minoofar, Payam N 06 Oct '17

06 Oct '17

Greetings and Salutations, I recently started using Chimera to view .cif files for metal organic framework (MOF) unit cells, and I get the impression that Chimera is not quite rendering them correctly. I thought I'd ask the community if visualizing MOFs is a priority for Chimera before I start whinging. (No, I'm not British.) If it is a priority, to whom can I mail the cif files in order to determine whether the problem lies with Chimera or with the file? Many thanks, Payam ------------------------------------------- Payam Minoofar, Ph.

help please!
by Nathan Goldfarb 05 Oct '17

05 Oct '17

Hello: I am trying to prep my ligand which is a tripeptide ending with a boronic acid. Chimera will not let me assign charges to it. It does not like the boron and says there is no Sybyl equivalent in the error message. Do you know how to get around this problem? Thanks! -- Nathan E.

Re: [Chimera-users] High Sierra fix

Hey there, Thanks for the information. However, the representation of atoms is still wrong in with High Sierra. I’m attaching an image of what I see. Have you received reports like this?. Is there any fix for that? thanks!! [cid:C21A9AF2-1CF2-4300-9F85-A65D871E91E9@mundo-R.com]

Chimera help for tomography data!
by Swetha Vijayakrishnan 05 Oct '17

05 Oct '17

Dear All, I am new to using chimera for EM tomography data. Essentially I am trying to create a movie with tomography and subtomogram data within a single movie. However, i am having trouble making and rendering the movie. I can open the tomogram tilt series (created in IMOD) and manually move it along using the planes option along the axis of interest. However i was trying to see if the Volume series option helps play it automatically but it doesn’t seem to do so. Is this the right way to do it? Any help on how i can play through the tomogram through the various planes back and forth and how i can create a movie will be greatly appreciated. Thanks and best wishes, Swetha Dr Swetha Vijayakrishnan MRC-University of Glasgow Centre for Virus Research (CVR) University of Glasgow, Sir Michael Stoker Building, 464 Bearsden Road, Garscube campus Glasgow G61 1QH UK Email: Swetha.Vijayakrishnan(a)glasgow.ac.uk<mailto:Swetha.Vijayakrishnan@glasgow.ac.uk> Phone: +44 (0) 141 330 4025 http://www.gla.ac.uk/colleges/mvls/supportforresearch/nerd/

Create oxime functional group
by Wikel, Jim 04 Oct '17

04 Oct '17

Hello, I recently had difficulties with creating a particular structure in Chimera. The SMILES is depicted below. The problem is I have not been able to represent the oxime portion of the molecule. I have tried to reset atomtypes, redrawing the structure, adding and deleting the atoms, passing it through other drawing programs, reformatting the file to other formats, but to no resolution. Chimera insists on adding a hydrogen to the oxime nitrogen prior to minimization. I am puzzled and suspect I may be doing fundamentally wrong. Any advice would be helpful. CC1CC(C)CN(C1)S(=O)(=O)C1=CC=C2C(=C1)C(=NO)C1=CC(=CC=C1C2=NO)S(=O)(=O)N1CC(C)CC(C)C1? Thanks you. jim

Re: [Chimera-users] Query (how to find H-bonds)

Dear Dr. Elaine Thanks! But I want to see protein and ligand (peptide) structure. I could not see ligand, the display shows only protein structure. The file I enclosed is docked result. Instead of ligand there is a dotted line in between the protein.....I could not see this before. The attachment file has (2 to 195 protein) and (1-7 peptide). I can see the individual structure in separate file but I could not see in same pdb file (docked result). The tutorial is not helping to fix the issue Please make me clear! ------------------ Sincerely Dr. Gurudeeban Selvaraj, Ph.D. Postdoctoral Researcher Center for Food Science and Technology School of Chemical Engineering and Environment Henan University of Technology, Zhengzhou, China Mobile: +86 1883 800 2927; +91 84890 55578 ORCID:http://orcid.org/0000-0002-7223-3853 Residence: Room No. 503, Foreign Teacher's Apartment, University Garden, Lianhua Street No. 50, Hi-Tech development Zone, Zhengzhou, 450001, China ------------------ Original ------------------ From: "meng";<meng(a)cgl.ucsf.edu>; Send time: Sunday, Oct 1, 2017 1:28 AM To: "Gurudeeban Selvaraj"<gurudeeb99(a)qq.com>; Cc: "UCSF Chimera Mailing List"<chimera-users(a)cgl.ucsf.edu>; Subject: Re: [Chimera-users] Query (how to find H-bonds) Dear Dr. Selvaraj, Probably you just need to display the atoms, command “display” or menu: Actions… Atoms/Bonds… show. This is just a general part of using Chimera.

Dear Dr.Elaine, Thanks for the information. It is working now but some of them I could not see hydrogen bonds (Intra). Now I could not see the ligand structure of the docked result in Chimera. I have enclosed file and snap shot of my issue.

One minor correction: for you, the lines will be whatever color is shown in the square color well near the top of the H-bond dialog… the default is a bright blue color similar to cyan. Elaine

Query
by Gurudeeban Selvaraj 28 Sep '17

28 Sep '17

Dear Support Team, Thanks for the academic free of Chimera. I have a doubt, how can I visualize H-bonding interactions of docked structure of protein-protein interaction. I used FireDock for docking studies. While running on FindHbond on structure/binding tool it says no H-bonds, but i click both shows something.....How can i see protein-protein interacting HBond and label it? For the reference, I enclosed two files. Thanks in advance! ------------------ Sincerely Dr. Gurudeeban Selvaraj, Ph.D. Postdoctoral Researcher Center for Food Science and Technology School of Chemical Engineering and Environment Henan University of Technology, Zhengzhou, China Mobile: +86 1883 800 2927; +91 84890 55578 ORCID:http://orcid.org/0000-0002-7223-3853 Residence: Room No. 503, Foreign Teacher's Apartment, University Garden, Lianhua Street No. 50, Hi-Tech development Zone, Zhengzhou, 450001, China

High Sierra fix
by Eric Pettersen 28 Sep '17

28 Sep '17

We have fixed the problem where interfaces that also showed 3D graphics (Rapid Access/main window; side view) weren’t working correctly on Mac OS X 10.13 (High Sierra). The fix is in the current daily build and the very latest version of the 1.12 release candidate. If you get either of those then it will be safe to upgrade to High Sierra, at least as far as Chimera is concerned. ;-) —Eric Eric Pettersen UCSF Computer Graphics Lab
