Dear Srs: I am a new user of Chimera, and I really like it! I would like to know if some of the developers could include a new format for density maps amongs those that are readable in Chimera: EM format. That would increase its use in our group, because now we need convert our density maps to mrc each time that we want to use Chimera. With my actual skills in programming, to write a plugin will take me like a year, and I think that should be relative easy for someone with experience. As attachment I am sending a text file with a procedure wrote in matlab to read EM format files. The syntax should not be so different from python. I could also provide you with test data. Thank you very much for your help, Dr. Julio Ortiz -- Max-Planck Institut für Biochemie Abteilung Molekulare Strukturbiologie Am Klopferspitz 18 D-82152 Martinsried Germany Tel: +49 (89) 8578 2034 fax: +49 (89) 8578 2641 --------------------------------------------------------------------- This message was sent using https://webmail.biochem.mpg.de If you encounter any problems please report to rz-linux@biochem.mpg.de
Hi Julio, I can write some Python code that will allow Chimera to read the "TOM toolbox for Electron Tomography" format. Is this format used with other software? Can you provide me an example file? What is the typical file suffix? For an example file you can email me something under 5 Mbytes, or put it on the web or an ftp site for me to download. I don't see any header parameters that indicate xyz pixel sizes in nanometers. This is useful in Chimera if you are for example docking crystal structures. If it isn't available I can just open the data in Chimera with pixel sizes defaulting to 1. I also don't see a field that encodes byte order. The machine coding field (Mac, PC, SGI, ...) is not a good way to deduce byte order, but maybe it is the best info available in the header. I don't understand the comments about "abandoned header". It sounds like this means there is no header on certain files. Chimera won't be able to read those. Tom
