Module import error

Hi There, I am trying to call a script with Chimera commands(saved as sample.py file) in another python program using os.system("chimera --nogui --nostats sample.py") and I get an module load error as below, import chimera ImportError: No module named chimera However, if I call the script with chimera it works, for eg., chimera --nogui --nostats sample.py typed directly in terminal is working. Can anybody help fix this error? Thanks in advance, Best Regards, Subha

Displaying Labels without displaying Atoms
by Nicholas Hyman 23 Jun '16

23 Jun '16

Hello, I have been working with labeling EPR restraints on a protein model through chimera. I would like to show a label of the distance between two residues and color it to show how well the model fulfills the restraint. I worked with the distance function, but I could not figure out how to change the color of the label through the command line, as there are quite a few restraints. I was able to achieve the desired result by writing a python script that makes a pseudo bond file. My issue is that in order for the labels to be shown, atoms must also be displayed. This creates a lot of complexity and makes the labels difficult to read. I was wondering if there is any way to keep only the ribbon display but add the labels in still? Please let me know what you think. Thanks, Nicholas Hyman *________________* *Nicholas Hyman* Vanderbilt University, Computer Science and Chemistry, Class of 2018 (770) 314-9270 | nicholas.j.hyman(a)vanderbilt.edu

Two things, can't seem to figure out how to: 1. Offset a residue label 2. In stick mode enlarge the stick or thicken it. Thanks A G Szabo

If I recall correctly, even though you don’t already have chain IDs, the parts separated by TER will be listed separately in the dialog and you can specify a new ID for each. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/editing/changecha…> There is also a “changechains” to do basically the same thing, but it only handles chains that already have IDs that are different from each other. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/changechains.html> I hope this helps, Elaine ----- Elaine C.

Hi, I am the developer of the PyChimera wrapper! Glad to know someone besides me is actually trying to use it! If you installed pychimera with pip or conda, you should have an executable called 'pychimera'. With it you can run the script directly with pychimera, like 'pychimera myscript.py'. Also, a bare PyChimera command ('pychimera') should bring up a Python interpreter where you can do "import chimera" just fine. Let me know if you are able to make it work!

Sorry about the typo. The environment variables of the system seem fine to me. I also tried calling Chimera from the same directory as the script and its working fine. However, calling the chimera script using "python sample.py" doesn't work and using absolute path to chimera didn't help too. I tried installing pychimera, but end up with the same kind of error when I try pychimera -i import pychimera ImportError: No module named pychimera Couldn't understand what's going on with these import modules. I would greatly appreciate any suggestions to solve this.

Chimera - Saving multiple files
by Elza Sofia Fonseca 20 Jun '16

Dear all, I am Elza Fonseca, a PhD student of the University of Porto and I am now learning to do dockings. I am using Chimera for open the results from SwissDock and I would like to save it like a multiple file. However I always get the same error message: "You must provide a file name that contains either $name or $number, which will be changed to the model name or model number (respectively) in the final saved file name". I don't understand what "$name or $number" means... May you please help me solving it? I apologize for my ignorance.

change default application for pdb files
by Cygler, Miroslaw 15 Jun '16

15 Jun '16

Hi, Since I have installed chimera on my mac laptop, it established itself as a default program to open pdf files. When I try to change the default to another software, it works only for one file at the time. Trying to make the change for all files with the .pdb extension by clicking “change all” button on the file info page strangely reverts back to chimera. This should not be happening according to Apple, as this is the standard way to change the default program to open specific file types. Any idea what is happening? Mirek
