[Chimera-users] How are chains paired in morphing?

Bobby Laird showed me a homo-tetramer with chains A, B, C, D that when 
morphed between two states with the Chimera morph conformations tool 
swapped two of the monomers.  In other words the 4 chains from one state 
weren't correctly paired with the 4 chains from the other state so two 
monomers exchanged positions during the morph.  The tetramers were built 
from dimers 1pfk and 2pfk by using the symmetry of the unit cell with 
other software (coot?).

How does morph conformations decide which chains to pair?
