WinXP SP1 python error on File -> Open

Hi, I'm getting a strange error when I start chimera and do file->open. This is the reply log: ValueError: list.index(x): x not in list (see reply log for Python traceback info) Traceback (most recent call last): File "C:\Program Files\Chimera\share\__main__.py", line 56, in ? value = chimeraInit.init(sys.argv) File "C:\Program Files\Chimera\share\chimeraInit.py", line 301, in init tkgui.eventLoop() File "C:\Program Files\Chimera\share\chimera\tkgui.py", line 2891, in eventLoop app.mainloop() File "C:\Program Files\Chimera\bin\lib\lib-tk\Tkinter.py", line 965, in mainloop self.tk.mainloop(n) File "C:\Program Files\Chimera\bin\lib\site-packages\Pmw\Pmw_1_2\lib\PmwBase.py", line 1751, in __call__ _reporterror(self.func, args) File "C:\Program Files\Chimera\bin\lib\site-packages\Pmw\Pmw_1_2\lib\PmwBase.py", line 1814, in _reporterror displayerror(msg) File "C:\Program Files\Chimera\bin\lib\site-packages\Pmw\Pmw_1_2\lib\PmwBase.py", line 1377, in displayerror _errorReportFile.write(text + '\n') File "C:\Program Files\Chimera\bin\lib\site-packages\Pmw\Pmw_1_2\lib\PmwBase.py", line 1747, in __call__ return apply(self.func, args) File "C:\Program Files\Chimera\share\chimera\tkgui.py", line 272, in _importModel clientSticky='ew') File "C:\Program Files\Chimera\share\chimera\tkgui.py", line 178, in __init__ OpenModeless.__init__(self, **kw) File "C:\Program Files\Chimera\share\OpenSave\__init__.py", line 185, in __init__ ModelessBase.__init__(self, **self.dialogKw) File "C:\Program Files\Chimera\share\chimera\baseDialog.py", line 378, in __init__ BaseDialog.__init__(self, master, *args, **kw) File "C:\Program Files\Chimera\share\chimera\baseDialog.py", line 220, in __init__ self.fillInUI(self.__top) File "C:\Program Files\Chimera\share\chimera\tkgui.py", line 181, in fillInUI OpenModeless.fillInUI(self, parent) File "C:\Program Files\Chimera\share\OpenSave\__init__.py", line 92, in fillInUI self.millerBrowser = MillerBrowser(parent, **self.millerKw) File "C:\Program Files\Chimera\share\OpenSave\miller.py", line 184, in __init__ self.makeMainColumn(initialdir, firstTime=1) File "C:\Program Files\Chimera\share\OpenSave\miller.py", line 509, in makeMainColumn titleMode=None, firstTime=firstTime) File "C:\Program Files\Chimera\share\OpenSave\miller.py", line 823, in __init__ index = normItems.index( ValueError: list.index(x): x not in list I have also posted the screenshot here http://linegli.mc.vanderbilt.edu/~sabuj/chimeraOpenError.jpg Also if I do "c:\Program Files\Chimera\bin\chimera.exe" file.pdb from the command line, then do file -> open, it works again. I've tried running it with and without precompiling modules after installation, but get the same result. I've downloaded the binary installation several times, done uninstall, then install, but I'm still getting the same error. I have not been able to re-create the error on another winxp sp1 machine. Any help would be appreciated, Thanks, Sabuj Pattanayek

Chimera, Python, WindowsXP or AMD64 conflict?
by David Piper 16 Sep '04

16 Sep '04

Chimera, Wonderful software package!!! I am running successfully on my desktop (Intel P4 2.8 GHz; Windows XP Professional) at the lab. On my eMachines M6807 notebook (Mobile AMD Athlon 64 3000+, 800 MHz, Windows XP home edition) although I can start Chimera and open a PDB file, as soon as I try to do anything (say rotate the molecule) I get an error message: Assertion failed! Program: C:\Program Files\Chimera\pythonw.exe File: togl.c Line: 960 Expression: res == TRUE && "Togl_MakeCurrent: failed" I did not see anything on your website addressing such a conflict, but hoped you might have a suggestion for me. Thanks, David Piper

3D viewing?
by Steven J Kolodziej 15 Sep '04

Hi; I was wondering if Chimera had an option for viewing files in 3D from a PC using glasses and if so what hardware is needed. Steve Kolodziej steven.j.kolodziej(a)uth.tmc.edu

ribbons of nucleic acids
by Ann Mullin 01 Sep '04

01 Sep '04

Hello, I am wondering how to adjust the ribbons of nucleic acids so that they follow the path of the phosphates or the sugars, anything but the averaged path they have now. I want to show the backbone as a ribbon with bases projecting out, but now some bases float about the backbone. Thanks for any help. Ann Ann Mullin Research Scientist Cell and Molecular Biology Dept.

Chimera and building molecules
by Elaine Meng 31 Aug '04

31 Aug '04

Dear Ben, We definitely agree that molecule-building would be a very useful addition to Chimera. Toward this functionality, Chimera includes hydrogen addition; also, the "bond" command has been implemented (and will be available in the next release). Chimera also includes the "swapaa" and "swapna" commands which "mutate" one sidechain or base to another, although they are not very sophisticated. I am not certain what you are referring to in MIDAS, which only had very rudimentary building capabilities and no ability to add hydrogens. The "addgrp" command did allow definition of new amino acid sidechains, but was quite unwieldy and not usable for building in general. Similarly, "addaa" could append one of the standard amino acids to the end of a peptide but was not generalizable to other types of molecules. If you could clarify how you were applying these tools, we might be able to prioritize developments accordingly. Thank you, Elaine =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Elaine C.

building molecules
by Ben Schuler 31 Aug '04

31 Aug '04

Dear Chimera developers, It seems to me that the manual formation of bonds and building of any type of molecules (not only proteins and nucleic acids), which was a strength of MIDAS, is not supported by Chimera. I would very much welcome an implementation of these features to make Chimera a real replacement for MIDAS.

chimera --send with multiple Chimeras
by Thomas Goddard 22 Jul '04

22 Jul '04

Hi Sandeep, If you have more than one Chimera running on a machine then "chimera --send" sends the file to the most recent one that is accepting connections. Each time you change the Favorites/Preferences/Web Data option to accept connections, that Chimera becomes the most recent. The way this works is there is a list of running Chimera instances that are accepting connections in file (on unix /tmp/chim_webinfo-<username> where <username> is your login name). This file lists the Chimera process id and port number it is listening on. The last line indicates the most recent Chimera that is accepting connections. I wouldn't recommend relying on info in this file since the implementation may change in the future. Tom

suggest OBJ export option
by Steven McQuinn 19 Jul '04

19 Jul '04

I'm really happy with Chimera, but vexed that every attempt to export a high resolution mesh via the VRML utility ends in a python failure. Have not tried exporting molecular models, only isosurfaces with 250,000+ polygons. What I use instead for export is VMD, which has an .stl export option, providing smaller file sizes than VRML. VMD is buggy on my XP system, requiring several attempts to export correctly. I use Chimera to get my isosurface settings right, then plug these values into VMD. SUGGESTION: If you provided an OBJ mesh export option, nearly every 3d application could utilize the product. The Wavefront OBJ format is the defacto universal exchange format, fairly small file sizes, retaining textures. Should be easy for you geniuses to program. Also, the stereo camera option never "takes." The walleye and crosseye cameras work OK but not the straight stereo pair, which I have to compose from the right and left images. Would like to send the development team some work samples. How do I do that? Please reply to my email address, as I don't read the list.
