Dear All, 

I have been trying to generate physiological relevant Hexameric structure of my recently solved trimer structure by using Symmetry Mates in Pymol, but I am unable to find appropriate hexamer even with all type of symmetry options available in Pymol (different distances)
Surface contact of dimer interface in the structure shows not much significant interaction between any two dimers. Is there any other way I can generate hexameric structure in Pymol or any other program which could be used for this purpose?

Any help will be highly appreciated, Thank you
