1. An apparatus, comprising:
a first flow cell assembly and a second flow cell assembly, each of the first and second flow cell assemblies including flow cells; and
a system including:
an imaging system;
a flow cell interface having a first flow cell receptacle and a second flow cell receptacle that support the corresponding first and second flow cell assemblies;
a stage assembly associated with a controller that causes the stage assembly to move the first and second flow cell assemblies relative to the imaging system; and
a pair of reagent selector valve assemblies, each reagent selector valve assembly corresponding to one of the first and second flow cell assemblies and having a reagent selector valve and a valve drive assembly, wherein the valve drive assembly drives the corresponding reagent selector valve during operation using shaped input signals to reduce vibration imposed on the stage assembly based on movement of the reagent selector valve,
wherein the reagent selector valve assemblies are carried by the stage assembly, and
wherein the imaging system obtains image data associated with the first flow cell assembly while the reagent selector valve assembly is actuated to flow reagent into the second flow cell assembly without substantially imparting vibration into the system.
