<TITLE>origin of sphere in MDmovie</TITLE>

<P><FONT SIZE=2>Hey Chimera-folks,<BR>
<BR>
I've got a nice movie with morph conformations, and then wrote a script that goes along with it that generates tranparent multiscale models (molmap) and displays a ligand with solid atom spheres for each frame in the movie. But I'd like to make a sphere that tracks along with the domain movement - it can't be transparent because the model is transparent already. The shape command looks like it can do this, make a sphere with a specified radius in mesh, but I can't figure out how to specify the origin according to a particular atom's coordinates, and then script it so that it tracks with the conformational changes in the movie. And it would be really cumbersome to write a bild file for each of the ~200 frames in the movie.<BR>
<BR>
I'm guessing something like "getcrd" will get the coordinates that I'd like to use for the origin but "shape sphere" doesn't allow me to specify origin.<BR>
<BR>
Alternatively I could render the atom I'm tracking as a radius 25 sphere, but am unable to display an atom as mesh.<BR>
<BR>
Can you point me in the right direction?<BR>
<BR>
Thanks,<BR>
