Initial angular assignments were obtained by manually docking available structures/reconstructions into extracted subvolumes using UCSF Chimera. These were further refined using the RELION 1.4 subtomogram averaging auto-refinement program, followed by focused refinement of individual subregions of the complex by application of binary masks and continuation of refinement. The resulting focused maps were stitched together using the "vop maximum" function in UCSF Chimera.
