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

substituting atoms
by simon chapman 03 Apr '18

03 Apr '18

Hello...for my Master's dissertation, I need to substitute a sulphur atom for an oxygen in a Molecular Dynamics simulation. The run works fine with my target molecule 1KF1.pdb uploaded into Chimera, but the substituted version sends quite a few error messages and won't run. It doesn't appear to recognise the novel S atom. Any help would be much appreciated...I've been stuck on this for nearly a week! Best wishes Simon

problem with ccp4 map fitting
by ela.nekardova＠gmail.com 29 Mar '18

29 Mar '18

Dears, I need to depict a map generated from CCP4/Sfall and a .pdb file corrected by Coot. I would like to create images by Chimera. Unfortunately, I cannot figure out how to make a correct view (in Coot, the map fits the molecule well), please, see the image/session in the attachment. I could not have found a guidance in the User's guide. Can you help me please? Thank you in advance for your help. Best regards, Michaela Nekardova Institute of Biotechnology CAS, v. v. i.

Reading and saving large files in chimera
by #TOFAYEL AHMED# 29 Mar '18

29 Mar '18

Hi Chimera developers and users, I have faced a problem with chain IDs and secondary structure while working on a large file. As I am refining my model in Phenix and visualizing in Chimera, I need to go back and forth between these two software and that creates a problem. To replicate my problem, here I have taken an example from PDB so that you get the idea. If I take model bearing PDB id 5IRE and apply "phenix.pdb.biomt_reconstruction" I can generate the complete virus icosahedral structure from the asymmetric unit. But when I open this complete virus structure in Chimera and save it back again the chain IDs get changed. Is there any work around to maintain the original chain IDs and therefore maintain the secondary structure definitions in the file header, after opening and thereafter saving using Chimera? Best regards, Tofayel NTU Singapore

Chimera command to set the volume contour surface threshold
by Irene 29 Mar '18

29 Mar '18

Hi, I am new using Chimera and am writing a script to generate automatically some volume contour surfaces. I would like to know if there is command to set from the script the volume contour surface threshold? I came across a post from 2006 (https://www.cgl.ucsf.edu/pipermail/chimera-users/2006-November/001121.html) where it was mentioned that such command did not exist by that time. I hope there is one now! Thanks a lot, Irene

Display channel as a filled body in Chimera

Selecting atoms and ribbons works as it should, but ctrl-clicking on surfaces has no effect whatsoever, be it before or after splitting. I could use Sc only because I selected the whole model using the command line. Splitting does work and I get a bunch of pieces, but I have no obvious way to select the distinct surfaces. Also, I?m afraid that using visiblePatches or any other method that involves selecting all residues that define the blobs would be extremely cumbersome in my case. As I said, if I ctrl-click on an atom or a ribbon, it gets selected, is highlighted in green, and the magnifying glass icon turns green as well. However, if I then ctrl-click on a surface, the selection is cleared (status bar displays ?selection cleared?). The graphics driver incompatibility actually seems a likely culprit. I think the previous time I used this feature, I was still on my old laptop. I am currently running Chimera on a 13-inch Early 2015 MacBook Pro (MacBookPro12,1). It has a built-in Intel Iris Graphics 6100 chipset. Could there be an easy hack/workaround on my side or a software patch? If not, then I guess I?ll go and finish that particular figure on another computer :) Cheers, Priit > On 15 Mar 2018, at 19:34, Tom Goddard <goddard(a)sonic.net> wrote: > > Hi Prit, > > I can select the split surface pieces of an MSMS surface with ctrl-click using Chimera 1.12.

The problem is either your machine?s graphics driver or one other idea it could somehow be some setting in your preferences file. You might try quiting Chimera, renaming your Chimera preferences file ~/.chimera/preferences so Chimera does not find it, and restarting and see if that helps.
