Symmetry expansion for protein unit in Helical Structure used in local refinement

Hi all, Each of my protein units is adhered to a tube based on specific helical parameters. I want to know if cryoSPARC can implement symmetric extension for each protein unit according to helical parameters, and later I would like to do local refinement on the protein units rather than the entire helical tube.
Thanks in advance!

Yes this is possible, and is documented in the symmetry expansion documentation:

And yes - after performing symmetry expansion using your refined helical parameters you can then perform local refinement (or 3D classification with a focused mask, if you need to clean up your dataset further)
