There's a comment in Segment.py:

# Get the chains from each model.  If they do not have the
# same number of chains, we give up.  Otherwise, we assume
# that the chains should be matched in the same order

It uses molecule.sequences() to get the chains.  Eric, does sequences() return the chains in input order, or is it random (eg hash order)?

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?
