Hello Elaine, thank you very much for the update! Serge On Thu, Sep 17, 2009 at 6:53 PM, Elaine Meng <meng@cgl.ucsf.edu> wrote:

Hi Serge, Dave, Jim, et al.,

In recent daily builds of Chimera, you can now define planes and measure distances and angles to these objects.  The planes are shown as disks, and you can perform plane-plane, axis-plane, and atom-plane measurements, in addition to the axis-axis and atom-axis measurements we had earlier.

The tool formerly known as Axes is now "Axes/Planes," and we anticipate it will eventually include centroids.  The updated documentation isn't there today but should show up tomorrow at <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/structuremeas/structuremeas.html#axes> and the interface is mostly self-explanatory anyway.

Each of you had asked about planes at some point (possibly a while ago), in case you are wondering why I addressed this message to you. 8-) Enjoy! Elaine ----- Elaine C.
