[chimerax-users] ChimeraX question

[Tom Goddard]

Hi Ryan,

  ChimeraX has a "morph" command.  Here's an example using it

	open 2vaa
	open 2vab
	matchmaker #2 to #1
	morph #1,2
	save morph.pdb model #3 allCoordsets true

Morphing of course only contains the atoms that are in both structures.  So if you have an unbound and a bound state, and the bound Y is only in one structure then it will not be included in the morph since there is nothing to morph it to in the unbound state.  You can delete chains that the two structures do not have in common before morphing, or you can use the same true option to the morph command "morph #1,2 same true" which will ignore chains which do not appear in both structures.

	Tom

If possible I would like to morph between the bound and unbound forms. I would like to do this with ribbon and the atomic models. Any advice?
