Sometimes one will alter the particle distribution in a two- or multistage simulation by means of shifting the slice centroids or to do a transformation. This could be done by importing a (Nx)6 vector and (Nx)6x6 transfer matrix. If N=1 (or the dimension omitted) than it is a global transformation for the whole beam. If N>1 then a distance has to be defined and genesis will interpolate the closes sample of vector and transport matrix to the position of the slice (e.g. with two vectors one can apply a chirp).
