Hi Mark, The error message says your script tried to open a file with the "open" Chimera command and that file does not exist. If you get the first image I guess your path to the directory must be ok. Not sure why your second file is not found. I guess I'd need to see both the script and a listing of the directory with the files to understand it. As for saving images, the Mac version is going to use the screen dimensions of the graphics window when saving an image if you don't specify the image size. The headless Linux version has no window so I don't know what the default would be. You should specify the image size in the image saving command. Tom
Hello,
I am doing some epitope analysis and I am generating images of each potential epitope overlaid and colored on the antigen model. I have a script that loops through a list of residue sets (epitopes) and uses chimera to generate the images.
The script works if I call it from within Chimera running on Mac OSX. I just installed the headless version on Redhat linux and was trying to modify my python script to run on the headless version and I ran into a few issues I would like some advice with.
1. Say I have ten sets of residues, which should produce 10 images. I get the first one, but then I get the following error:
Traceback (most recent call last): File "/opt/bin/Chimera64-1.6.2rc/share/chimeraInit.py", line 686, in init midas_text.doRunScript("runscript", script) File "/opt/bin/Chimera64-1.6.2rc/share/Midas/midas_text.py", line 2037, in doRunScript execfile(scriptPath, scriptGlobals) File "batchEpitopeModel3.py", line 144, in <module> callChimera(data[ab][4],data[ab][5],fn,dn) File "batchEpitopeModel3.py", line 29, in callChimera rc("open " + trimer) File "/opt/bin/Chimera64-1.6.2rc/share/chimera/__init__.py", line 2426, in runCommand makeCommand(*args, **kw) File "/opt/bin/Chimera64-1.6.2rc/share/Midas/midas_text.py", line 69, in makeCommand f(c, args) File "/opt/bin/Chimera64-1.6.2rc/share/Midas/midas_text.py", line 1427, in doOpen modelArg, noprefs) File "<string>", line 1, in <module> File "/opt/bin/Chimera64-1.6.2rc/share/Midas/__init__.py", line 1937, in open raise MidasError('%s' % msg) MidasError: No such file or directory
Error while processing 'batchEpitopeModel3.py': MidasError: No such file or directory
File "/opt/bin/Chimera64-1.6.2rc/share/Midas/__init__.py", line 1937, in open raise MidasError('%s' % msg)
It seems like Chimera terminated my script, even though it should be executing a loop.
2. The images that are generated on the Mac are large, hi-res pngs, but the images generated by the headless version are very small, low-res versions. I am not setting any image dimensions, are the defaults different between the two versions?
Thanks for any help. I can post (or email directly) part of my python code if that is helpful.
