Docking the border segments of coiled coils in parallel orientation

Dear Sir or Madam,

I need to dock the border segments of two coils (from four ones) from each of two homotetramers in a parallel orientation (I mean, that docked helix bundles should lay in one direction).

I would like to find out, which kind of files should I use and/or parameters in that files should I write for docking these segments in a proper way?

I will be sincerely grateful for your responses and advises and I am looking to it.

Best regards,

Corvin.
