Thank you very much, I can see the side chains move! But still the  heme group (in hemoglobin) can't be made to move.

I say that because if you see something not moving, it might be the original structure.

> Since your input structures are the same protein, if each one includes the sidechain atoms, the morph should contain all the same sidechains and they should move from one position to the other during the morph.  They may not be displayed automatically, however. Try displaying all atoms (again better to hide the other structures first) to make sure of what is there.
> About the ion: even if the ion is in both structures, it may not be in the morph if you are using an older version of Chimera.  However, there have been some fixes, and I believe if you are using Chimera 1.6 or newer, the ion should be included.  The fix I'm thinking of was 6 months ago and is described here:
