Hello,

I am trying to make a morph between PDB entries 9SKS and 9SKT. The protein does what I want, but I can't find out how to include the active site :ZN in the interpolation. This ion is consistently numbered between both structures, and I give model numbers to the morph command, which should select the entire models including their ions. Nothing about this in the documentation. What am I missing?

If interpolating ions with morph is impossible to do for some reason, then it would be helpful to list it in the "limitations" section of the command's documentation.

Thank you in advance,
