Sensitivity/Specificity Analysis. Results of the simulations obtained by adding an artificial pattern on Chr1 real noise. A) Detection is shown for varying intensities of the pattern for 4 different patterns (2 telomeric 1p patterns of differing length, than a whole 1p and a whole chromosome pattern). Specificity is measured as detection at intensity 0. B) The four detection lines correspond to 4 simulation studies where the pattern was added to 2, 4, 8 and 13 out of the 27 arrays in the data-set.
