Editing Cealign plugin (section)

=== It Worked A Second Ago! ===

If you were using cealign (or alignto) and now the commands don't work -- that is, they return an RMSD, but don't actually superimpose the objects, then you have a simple problem dealing with states.  Most likely the cause of this oddness was (1) when you issued "cealign prot1, prot2" one of them was actually an ensemble of states or (2) you are trying to align to proteins with only one state, but are not looking at state one (because the last protein you were considering had more than one state and you quit editing that protein on a state that's not state 1).  To fix this, use the rewind button to get the proteins back into state 1 & reissue the cealign/alignto command.
