[phenixbb] unassigned densities

Dear colleagues, Is there a way to assign cryo-EM densities not included in the model sequence? Do you have any tools that can help? More closely, is there a way to screen the cryo-EM map + model, point out the unassigned densities, and provide the possible structures to fit in (e.g., water molecules, etc.)? Thank you. Kind regards, Dmitry
