Hi guys, I'd like to select two precise beta strands of my prot and I thought it would be easier to do so from the sequence editor. Unfortunately, I can't find a way to select different parts of the same protein in the sequence editor; I alwys select the full length between first and last selected residues whatever combo I use (shift, ctrl and so on). Is it possible to do this in the sequence editor?

Recent email address change caused the first try to bounce, so I resent it.
I've loaded a file (2rjp.pdb) with 4 chains and want to split it into 4 models so I can align them. But "split" returns:
unrecognized command: "split"
What am I doing wrong?

Hi Evan, You must be using a version of Chimera older than the "split" command. If you use the documentation that came with your download
(opened from the Help menu) it should be fairly synchronized with your software and you won't get confused by features you don't have! However, in this case, just get a newer version.
The pages at our web site under http://www.cgl.ucsf.edu/chimera/ docs/UsersGuide/
are "development documentation," which I am constantly changing as Chimera changes. It will generally have newer things than your downloaded software.
The pages under http://www.cgl.ucsf.edu/chimera/current/docs/ UsersGuide/
are documentation for the most recent production release (currently
Nov 2007) and I see it also lists "split". So to use that feature you can get that production release: http://www.cgl.ucsf.edu/chimera/download.html#production
There are also much newer "daily builds" although they are essentially untested and exist mainly to provide access to the very
latest developments. http://www.cgl.ucsf.edu/chimera/download.html#production
I just tried your structure in the production release and last night's daily build; "split" worked in both, so you should be all set! Elaine ----- Elaine C.

Hi Jeff,
The trouble obtaining opaque volume planes is not related to volume plane display being built into the volume dialog. It is related to a change I made in how transparency is handled in solid mode back in Aug 2007.
Today I changed transparency in "solid" style volume rendering so it is easier to obtain completely opaque data planes. In tonight's builds (if they succeed, may not since we are switching to Python 2.5 today) you can obtain completely opaque volume planes by using the "Brightness and Transparency" panel of the volume dialog to set transparency to 0. This transparency value represents the fraction (0-1) of the depth of the volume required to produce opacity to the degree indicated by the height of the yellow curve on the histogram. In other words it modulates the overall transparency. But until today it was arbitrarily deciding not to modulate the transparency if this depth was less than one grid spacing. This meaning of the transparency factor was introduced in August 2007, and prior to that the transparency factor just scaled the opacity given by the yellow curve.

hi Tom,
in the older (plug-in) volume planes tool, I was able to generate images that were opaque planes. I don't seem to be able to do this anymore, even with transparency = 0. is there a way for me to do this in the current Chimera?

thanks,
do you know when tonight's builds will go through, I will test it at that point to see if the functionality made it in

The Chimera nightly builds usually run around 9 pm pacific standard time (california). The nightly build download web page has the date for each build, and that will not be updated if code checked in during the day does not compile. Code changes checked in before about 8 pm makes it into that night's build.
