Abstract
A method of processing probe trace data to determine a measure of correlation of a probe trace with other probe traces comprises obtaining a map that associates a parameter space with a plurality of pixels, wherein at least one correlation value is assigned to each of the plurality of pixels, and determining a correlation score for a probe trace by mapping the probe trace to at least one pixel of the map and determining the correlation score for the probe trace from at least one correlation value of the at least one pixel to which the probe trace is mapped.
