Hi Elaine, Regarding point (2): changing the content of the label, other than using the gui menu, can I do it through command line? I am dealing with quite a large number of residues for labeling. So if I can automate the process through scripting will be good. I came across this command rlabel which allows me to label the residues, but it seems to, by default, print out labels with both residue position along the chain and 3-letter code, which I would like to omit. I read its documentation but doesn't seem to allow me to change the content of the label printed out through this command. I am exploring labelopt also, but I am not too sure if it is helpful. Please advise, thanks! =] Cheers, sum From: Elaine Meng [mailto:meng@cgl.ucsf.edu] Sent: Wednesday, October 06, 2010 12:10 AM To: Sumitro Harjanto Cc: chimera-users@cgl.ucsf.edu Subject: Re: [Chimera-users] changing the content and colour of labels Hi Sumitro, 1. yes, you can change the color of the labels only, using either the "Actions... Color" menu or the color command. If menu, in version 1.5 (daily build), choose "Actions... Color... all options" and in that dialog set "coloring applies to" to "residue labels" and then do the coloring. In earlier versions, choose "Actions... Color... residue labels" and then use that menu again to do the coloring. Either version, you should probably change back from "residue labels" to "all of the above" again after coloring the labels to avoid later confusion. If command, you would just put a modifier right after the color name. Modifiers include ",l" (letter ell) for labels, ",lr" for residue labels, etc. as documented here: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/color.html> Example: color hot pink,lr :52 to color residue label only of residue 52 hot pink. No space after the comma. 2. yes, use menu item "Actions... Label... Residue... custom" to set custom residue label contents. Documented here: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/customlabel.html> Best, Elaine ---------- Elaine C.

I have managed to get the colours on the residues. Now I have another problem pertaining to the label. 1. Is there a way to change the colour of the label such that it is different from that of the residue..? 2. How can I change the information on the label such that only the residue's position is shown (omitting the residue's name/type)? Thanks.
