[Chimera-users] PDB morphing

[Dougherty, Matthew T.]

we tried the one file approach, did not work out.
will try again.  does it make any difference about the chain id or atom number?

Hi Matt,
Currently each input conformation for morphing can only be one model.   
Chimera considers each input file to be one model (or more, if the  
file contains multiple sets of coordinates delimited with MODEL/ENDMDL  
records).

Without code change, the only way I can think of is to put each entire  
structure of 24 monomers in a single PDB file.  This may be a pain, as  
you would probably want to give each monomer a unique chain ID so that  
all residues in the "model" are still uniquely identifiable by residue  
number/chain ID.  Then you would have one file per conformation.

Since I haven't actually tried this, I recommend trying on a subset of  
2-3 chains before going to all the trouble of putting all 24 in a  
file!  Maybe the others can come up with a more elegant solution.
Best,
Elaine
