Interactive Shifting of particle alignment center in 2D

Features and Functionality
1

Hi CryoSPARC Team,

This may just be more brainstorming than feasible but who knows. More often with proteins I am working with due to odd shape or being localized on a nanodisc/tube or liposome, centering the pick is an issue. While Topaz and cryolo do a good job, it is really challenging. What happen usually is the membrane bound or odd shaped molecule defines a center based on some high detail/bright spot. If I increase box size to be big enough and some other strategies, I can eventually center it and train better models.

Would it be possible to have an interactive 2D classification job in which the circular mask can be shifted across the 2D square. The output of that jobs would be particle stack with coordinates shifted to reflect the back calculated new pick center.

Thanks,
Bassem
