Number of Preprocessing GPU Workers (minimum one) selected here will determine how many cryoSPARC Live workers will be spawned. Live workers perform preprocessing of incoming movies, including motion correction, CTF estimation, thumbnail generation, particle picking, and particle extraction. Each cryoSPARC Live worker will allocate one GPU to its main process and use this continuously unless the worker is killed (by way of pausing the Session). The number of preprocessing workers can be changed by modifying this value. The new number of workers will be spawned once the Session is paused, then started again.
