Toolbar and Favorite on PC

Hello all, when running chimera on my PC (windows XP), my toolbar stopped being displayed. If I uninstall and reinstall chimera, my toolbar comes back until the next reboot. How can I fix that ? Is there to restore my preferences after launching chimera?

Although this does not relate to your question on licensing, is there any particular reason you're using such a complicated workflow? Chimera can be used to generate basic geometry (sphere/cylinder) from PDB files via povray, but so could any import system you have for the 3D modeling software. You would also lose the benefit of chemistry-centered structure for manipulation or selection: chains, residues, etc. I've been using Blender to handle complicated chemical models for a while now, and it wasn't that difficult to implement the import of various data types. With BioPython pdb files become trivial, and volumetric data sets are (very) difficult but possible.

changing center of rotation
by Jonathan Hilmer 30 Oct '06

30 Oct '06

Although I haven't used EMAnimator, you can set the center of rotation within Chimera using the Set Pivot action: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/menu.html#actpivot There's also Tools/Movement/Rotation, and lastly, you can edit structures to insert artificial points at extreme high/low XYZ locations, which will in effect manually set the center used via the 'center of models' option. I wouldn't recommend the last option unless you have a good reason to do so, but it does work.

Hi Wendy, Here are some Chimera commands that are useful for making movies with Movie Recorder: http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/recorder/moviecomm… Here's a fancier Chimera movie script example. http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/recorder/1gfl.com Here is the documentation for the Movie Recorder dialog and movie command: http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/recorder/recorder.… http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/movie.html Tom

rotating molecules for movies
by wendy ochoa 30 Oct '06

30 Oct '06

Can anybody tell me how to use EMANIMATOR to make a movie of a molecule rotating. If I use the spin option, it uses the axis (0 1 0) but my molecule is not center at 0 0 0. Is there a way to fix the rotation center to the center of the molecule, or to the center of the view? Thanks

Hello all, I want to generate the electrostatic potential map using Chimera. I tried through Delphi controler, however i am repeatedly getting an error as follows. I have successfully installed Delphi.

viewing grid density
by bala 26 Oct '06

26 Oct '06

Hello all, 1) I hve generated a solvent density map using Amber8 in XPLOR format. I am able to open the map in chimera. I hv also generated a refernce pdb file. Now i have to fix the reference structure of my molecule in the density map. I tried many options but i couldnt do that. Someone pls suggest me how i should do the same. 2) Also i am not clear with the meaning of the threshold levels given in the histogram. Although i could see the difference in the density map by sliding the vertical bar to various postions, i am getting what it can tell us exactly. Which is the most suitable threhold level etc. 3) Someone pls give me the link for the chimera mail list archive...i am unable to locate it. Bala

To except box information in MD movie
by Atsutoshi Okabe 25 Oct '06

25 Oct '06

Hello, I viewed Amber format trajectory files ( topology/parameter file and trajectory file ) by MD movie. But I got the figure( attached file) I didn't intend. I think the reason is to read box information in the Amber trajectory file . How can I except the box information in MD movie window ?

To color atoms
by Atsutoshi Okabe 24 Oct '06

24 Oct '06

Hi, I visualized one ligand molecule (a kind of sugar) written by PDB format within chimera. But all atoms have non color(attached file ) I want to color these atoms (i.e. the oxygen has red .) Could you please teach me how to color atoms?
