Hi, Is it possible to read the PDB file of the molecule directly from chimera? Thank you Eduardo Sanz

Hi everybody, Is there any way to give a name to a selection from the command line? Same as: *Select... Name Selection...* <cid:part1.01070107.06060601@terra.es> but from the command line. Thank you.

further levels of detail in low-res surface of a single chain Multiscale model
by Klinkhardt＠em.uni-frankfurt.de 05 Apr '06

05 Apr '06

Hello, I would like to divide/define the low-res structure of a multiscale model which contains only one chain. I need further levels of detail in this single chain (preferentially all single nucleotide bases as small podgy shapes and the backbone of phosphate-sugars as an irregular rope) so I can can animate the resulating smaller units later. In your online hept (documentation) there is written that a python script like #bluetongue.py# can create a multiscale model with further levels of (individual?) structure. I have opend the python script but unfortunately I am no programmer so I am not able to modify this script to my requirements. Is there a #more general# script which I can use for my chain or any other workaround?? Thanks a lot in advance, best regards Ute Klinkhardt

question about CHIMERA
by Guy Nimrod 04 Apr '06

04 Apr '06

Hello, I am a PhD student in the department of Biochemistry of the Tel-Aviv University and often use your great application, CHIMERA. Is it possible to view on chimera the selected part only? Regarding this, is it possible to split a model to its units (so each chain/ligand) will be considered as a model? Thanks Guy Nimrod http://ashtoret.tau.ac.il/~nimrodg

Please consider adding PyTables to Chimera
by David E. Konerding 04 Apr '06

04 Apr '06

Hello, Recently I have been converting most of my scientific data to the HDF5 format. HDF5 is a powerful, high performance data format library. I found an absolutely wonderful open source code, PyTables, which provides an HDF5 interface. It adds enormous value to HDF5 by making it much easier to use, and exposing a lot of the complex functionality that HDF5 supports (such as variable-length records). http://www.pytables.org/moin I would really appreciate it if you guys would consider adding PyTables. I would definitely convert a lot of my existing extensions and processing tools to use PyTables- for example, when I analyze trajectories to find hydrogen bond data and use that to render long movies, PyTables makes it a lot easier (I already used the Chimera headers to build my own copy of PyTables on Linux, but it would be a lot more painful to do on Windows). PyTables depends on numarray (although it also provides Numeric Python support). I'd like to see numarray in Chimera as well (although I could live with just Numeric support) Dave

What is Chimera's trigonometry convention ? How can get angles out of the rotation matrix (saved with "matrixget") ?

Different colors for individual chains within a model
by Karpen, Saul J. 31 Mar '06

31 Mar '06

Dear Chimera group, Simple question from a new user--How do I distinctly color ribbon representations of different chains within the same model? Thanks, Saul J. Karpen, M.D., Ph.D. Baylor College of Medicine

Thanks to all for the help. I have transparent images now. Thanks, Scott Weldon, M.A. Supervisor, Medical Illustrator Division of Cardiothoracic Surgery Michael E.

Here are the relevant pages of the Chimera User's Guide: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/startup.html http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/options.html Tom

Question about background transparency
by Weldon, Scott 28 Mar '06

28 Mar '06

Hello, I'm not having any luck using command line to change the background to transparent. I've tried "-bgopacity" and "bgopacity" and both say it is not a valid command. Would you please provide the exact syntax that should be entered to achieve this? Does this need to be entered before the PDB file is opened? Thank you for your help, Scott Weldon, M.A. Supervisor, Medical Illustrator Division of Cardiothoracic Surgery Michael E.

ses volume
by Charles Spink 21 Mar '06

21 Mar '06

Is it possible to get a calculated volume for the solvent excluded area for a protein or dna? I know the volume for a solvent accessible surface is possible through "measure volume" command. What about SES volumes? Thanks, Charlie Spink
