Hi,
Orientation diagnostics allows one to input a symmetry string, as the symmetry affects the view coverage necessary for adequate sampling.
It seems like the same also ought to be true for helical symmetry, but there is no option currently to evaluate helical symmetry during orientation diagnostics. Would this be worth incorporating?
Cheers
Oli
Hey Oli!
You should be able to do this by running the particles through Symmetry Expansion prior to Orientation Diagnostics (and leaving the diagnostic symmetry as C1). Also note that this will not affect cFAR/Relative Signal.

that makes sense, thanks @vperetroukhin! That will lead to quite a long job for high symmetry orders though (e.g. not uncommon with small rise to have an order of 100+… leads to 10’s of millions of particles very rapidly)
Hey @olibclarke – coming back to this older post just to confirm that we’ve decided to keep helical symmetry out of the orientation diagnostics job for now (in favour of the Symmetry Expansion upstream option I mentioned above).
Note that the Symmetry Expansion job will not actually duplicate any image data, so hopefully 10’s of millions of particles is still manageable as an output.
