There isn't any Chimera command to identify the center of mass or a
density map or place a marker/atom there. But that seems useful. A
Python script can easily do it. I'll see if I can give you a Python
script at the end of today, or maybe add an operation to the Chimera
"measure" command to do this job.<br>

<p class="MsoNormal">Hello,<o:p></o:p></p>

<p class="MsoNormal">I got a volume map that I segmented in 4
parts. Now I wanted to measure how the parts are coordinated
to each other. As the Axes/Planes/Centroids menu can only
create planes by atoms I wanted to place atoms in the mass-
center of each segment. Is there any way to realize that?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Or do you have any other way to measure the
angles. To explain what I’m trying to measure: Example you
have 4 segments, I call them a b c d. I want to measure how
the axis that is formed by a and b, forms an angle to c and d,
or how ist he angle of the plane formed by a b and c compared
to ab and d . All for segments are basically the same objects
just turned and rotated.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With best regards<o:p></o:p></p>
