A control pedal unit for a vehicle having a support structure, a pedal connected to the support structure and a detection mechanism responsive to movement of the pedal for generating a signal corresponding to the position or change of position of the pedal. The method continues with the processing module creating a rebuilt encoded data slice for the encoded data slice based on the rebuilding information. Such transgenic mice are useful as models for disease and for identifying agents that modulate gene expression and gene function, and as potential treatments for various disease states and disease conditions.
