Hi Dieter,
Our academic licenses allow you to have cryoSPARC running on a single machine at a time. If you’d like to run experiments on another machine, you will need to deactivate the existing machine and then run a job on the new one. You can switch between multiple machines at any time, but please keep in mind you can only run jobs on a single machine at a time.
