[Chimera-users] creating a symmetric tetramer from a PDB file for a monomer?

[gtseng at mail2.vcu.edu]

Dear Chimera creators:
    Could you please let me know whether it is possible to create a
tetramer structure with 4-fold symmetry from a PDB file for a monomer?
Specifically, I want to create a structure of a voltage-gated K
channel which has 4 monomers surrounding a central pore symmetrically,
beginning with the PDB file for a monomer. There is no 'transformation
matrix' in the PDB file to allow me to create the tetramer easily.
    Thank you very much for your help!
