Dear James (Gleb?),

You can tile models (2 or more) to lay them out in the plane of the screen.  I would recommend saving the superimposed position first, however, since you will probably need it later.  For example, if you have the models superimposed, commands something like:

savepos pos1
tile

<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/savepos.html>
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/tile.html>

By default, tiling also sets the models to rotate independently around invidual centers instead of a single global center of rotation. If you didn't like the spacing or wanted to try some of the other tiling options you could reset to the superimposed position and then try again, e.g.

reset pos1
tile # spacing 0.8

<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/reset.html>

Although there is a ~tile (un-tile) command, it untransforms everything, so if you had done prior separate transformations (like superimposing one protein on another), it would mess that up.  That's why using savepos/reset is generally better.  Both ~tile and the savepos/reset approach will restore the rotation-center behavior.

I hope this helps,
Elaine

I didn't find this in the tutorials and will be very thankful if someone suggest me with this together with the list of some other commands usefull for the analysis of the aligned structures.
