[Chimera-users] moving parts of a density map in a Movie

Hi Anindito,
If you just want to translate a specific map in one direction and then back to where it was, you can simply use the “move” command with its model number, for example translating model #1 200 distance units (usually Angstroms if that’s what your maps are in) along vertical axis over 100 frames:

move y  200 100 models #1
move y -200 100 models #1


See the manual page for details. You can translate along any vector, and of course you would change the distance value and number of frames as you like, and move more than one model at a time.

However, if you have more complicated ideas of exactly where you want each map to go, you would have to place them by hand and use savepos to save/name each set of positions, which can then be restored with “reset” or “fly".  

Each “savepos” position includes all the models, so you can’t only move one model when it has all of them in different places.  You’d have to save a new position for each model position change.

There is also “play radial” for radial explosion outward, but it is for multiscale surfaces, not map surfaces.

I hope this helps.

For making a movie to show the different components and their organization- What will be the commands to make the individual density maps to move  out of their position (in the composite map) and fly back in, (one or multiple density maps  at a time).
