[Chimera-users] Coloring an specific area along a morphing serie among several maps

Hi Ana-Lucia,

  You can use a color zone around a marker to color a specific region.  It will be harder if that region moves so much that the marker needs to move with it.  Here is the simple case with the marker fixed — the attached command script makes an example movie with two maps, resulting movie attached.

Then, you could use “vop morph” commands to play the map morph, “modeldisp” and “~modeldisp” to show and hide marker sets by their model numbers (since marker sets are implemented as molecule models), and “scolor zone” for coloring zones to match the markers.

Although there is also a “morph” command to morph between sets of atom coordinates, it is meant for use with biopolymer chains (proteins, DNA, RNA) and it may not work for marker sets.  If you try, here is a previous post about synchronizing map morphing with atom morphing:

My complex has an specially flexible domain   and  I need to highlight this area along the morphing sequence of the six maps. I suppose that this can be done using the markers and color zone options, but I don't  know how to implement this orders in the .cmd script of my movie.  Thanks in advance for your help.
