Re: [scipion-users] Removing empty particles

[Grigory S. <sha...@gm...>]

Hi Dmitry,

I haven't used that protocol so can't comment on it. By empty particles do
you mean completely black particles with 0.0 or some particles with noise
inside? You could use relion_image_handler with the "--stats" option to
find the former ones.

Getting rid of second ones is more difficult.

Best regards,
Grigory
