1. A method for simultaneously editing up to 10,000,000 genomic sites in a population of live cells in an automated stand-alone multi-module cell editing instrument, comprising the steps of:

  • providing a population of live cells in a receptacle configured to receive the live cells;

    providing first nucleic acids comprising up to 10,000,000 editing cassettes to one or more receptacles configured to receive first nucleic acids;

    growing the live cells in a growth module to a desired optical density to produce grown live cells;

    filtering and rendering electrocompetent the grown live cells in a filtration module to produce electrocompetent live cells;

    transforming the electrocompetent live cells in a transformation module configured to introduce the first nucleic acids into the electrocompetent live cells to produce transformed cells;

    providing conditions in a nuclease-directed editing module to allow the first nucleic acids to edit nucleic acids in the transformed cells to produce edited cells; and

    using an automated liquid handling system to

         1) transfer the first nucleic acids from the one or more receptacles configured to receive nucleic acids to the transformation module,

         2) transfer the live cells from the receptacle configured to receive the live cells to the growth module,

         3) transfer the grown live cells from the growth module to the filtration module,

         4) transfer the electrocompetent cells from the filtration module to the transformation module, and

         5) transfer the transformed cells from the transformation module to the nuclease-directed editing module without user intervention.
