Hi guys, I saw on the mailing list some information on exporting/importing 3D files. However, I can't really figure out what would be the best way to export chimera scene so that blender can import them. Is the x3d format the best? Which plug-in do you use? Is there another way better?

Hi Francesco, you can change the background colour in Chimera: Actions->Color-
background, then Actions->Color->[choose your colour like you would for colouring atoms etc.]. Then just save your image as usual and it should be on a white background.
Also, some of the Publication Options in the Presets menu automatically set the background colour to white.
Maybe there is a command line call for changing the background as well? I don't know...

When mapping protein residues around a ligand I would like to have a printout of the enlarged binding site area, so as to put remarks by pencil on the printout. However, on a white background, in order to save ink. Is that a problem of working out the image (I have Gimp only, of which I never gained expertise), or can Chimera provide directly?
Thanks francesco pietra

Utilities... 2D Labels): <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/2dlabels/2dlabels. html
Since these labels don't move when you rotate the structure, you would first find the position you want to show in your figure, and then add the labels. Alternatively, for labels in 3D that move with the structure, you could just label one atom in each helix and then manually change what is in the label (for example with "Actions... Label... other..."). However, for figures I think 2D labels are much better, since they allow more control over location and can include symbols such as Greek letters, and it is easier to change their sizes and colors. Some example images with 2D labels: <http://www.cgl.ucsf.edu/chimera/feature_highlights/2gbp-bfactor.png> <http://www.cgl.ucsf.edu/chimera/feature_highlights/2fma-density.png> <http://www.cgl.ucsf.edu/chimera/ImageGallery/entries/cavities/cavities-larg e.png

I would probably start by using either zones or Find Clashes/Contacts with a conservative cutoff to select all the residues you want to keep, which would probably also include several extra residues. If you used Find Clashes/Contacts, one option selects the contacting atoms, and you would press the keyboard up arrow to promote the selection to whole residues. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#zones
<http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/findclash/findclas h.html
Next, invert the selection (for example with Select... Invert (all models)) to include the residues you do NOT want, then undisplay them (for example with Actions... Atoms/Bonds... hide). Then you can manually get rid of the few extra residues here and there: Ctrl-click to select one atom or bond in an unwanted residue, press keyboard up arrow to promote to whole residue, undisplay as before. Repeat as needed. I don't know if you meant you wanted to just undisplay atoms or actually delete them. If you wanted to delete them: you could save PDB(s) and choose the option to include only the atoms that are displayed. Alternatively, you could use the approach described above except instead of undisplaying atoms, deleting atoms (for example with Actions... Atoms/ Bonds... Delete) and then save PDB(s). <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.ht ml#deletion
