Strange and inconsistent Chimera behavior recently on W7/Nvidia OS
by Boaz Shaanan 08 Feb '19

08 Feb '19

Hi, I started to have strange and inconsistent behavior of chimera when I open PDB's. My system is W7 with Nvidia 840M graphics card (which has been functioning fine for nearly 3 years). I am running the latest daily build but noticed this strange behavior with previous versions as well as the production one. I attach 3 snip pictures, the first two are of pdb files opened, one OK (as usual) and the other distorted. The 3rd snip pictures is of the Nvidia debug when I start Chimera in command file as chimera.exe --debug-opengl. It became quite a lottery for me as for how pdb file will open. The .py files open OK so far as I recall. Please help me with this recent mystery.

I have superposed two structures and printed the attached figure with sequence superposition and Ca RMSD. Is there a list of residue by residue RMSD as well? I can’t find it anywhere apparently. Thanks Vito

Running vina locally
by Sam Freeman-Fox 06 Feb '19

06 Feb '19

Hi, I am looking at running docking simulations locally, and see that with the vina command line execution (*vina* *docking* *receptor* *recmodel* <frameatom_spec.html> *ligand* *ligmodel* <frameatom_spec.html> *options <#options>) *one of the available options is to change the backend from using the Opal web service to a local executable. Could you advise on where I would be able to download such a local executable in order to get this to run. Many Thanks, Sam Freeman

How to color density maps using markers?
by Ahmad Khalifa 05 Feb '19

I know I can use volume tracer to place markers in the density. There was a tutorial explaining the use of these markers to color certain areas of my density map, however I lost track of it. Best regards.

Help: 'broken pipe' error
by Mungo Carstairs (Staff) 04 Feb '19

04 Feb '19

Hi there, I'm experimenting with Jalview as Javascript talking to Chimera over the latter's REST server. The first few 'list models' commands work fine, but when I send a command 'open cifID:4zhp' I (usually but not always) get an error '[Errno 32] Broken Pipe' in Chimera. Is there a clue in the stack traces below as to the reason for this? Thanks. Chimera 1.12 (build 41481) on OSX Sierra 10.12.6.

Slicing/Subdividing Models in Chimera
by Mauser, Jonathon 04 Feb '19

04 Feb '19

Hello, I am working on developing a new suite of flexible multimedia 3D printed protein models using Chimera to process to .stl. I am trying to make a sort of “anatomical” cutaway of an enzyme complex where I can slice the model in chimera along a certain plane and print the sections with caps, but am running into problems. I have tried simply clipping into the model, which does essentially what I would like to do, but I don’t know how to delete everything that I’ve clipped out of the model. When I export my scene, it still exports the whole model instead of the clipped depiction. Ideally, I would like to just cut the pdb in half to start with more advanced cutaways coming later. Do you have any idea how this might be accomplished? Thank you!

After merging two structures in Coot, chimera is showing a chain break at one end where I merged my molecule. The other end is displayed correctly. How can I fix that?

I'm trying to combine a few chains from different models. I'm using: combine #1:.k,.e #2:.k,.e. I'm getting the above error, and I'm not sure why my selection isn't working! Regards.

question
by Craig Scoville 31 Jan '19

31 Jan '19

Dear Staff -- I am interested in using Chimera but have a question regarding its use. I am interested in looking at the shape of small polypeptides --usually ranging from 5-20 amino acids -- does this program allow me to input amino acid sequences and then look at confirmational shapes? make substitutions and then compare confirmational shapes? Does the proprietary nature of my work prohibit me from using Chimera? Sincerely, Dr Scoville
