Minimum cDNA probe intensity thresholds differ in each sample set. (A,B) CEU sample set, (C,D) YRI sample set, (E,F) FIB sample set. (A,C,E) The average expression (both cDNA channels) and AI were determined for all uninformative females (CEU, n = 30; YRI, n = 31; FIB, n = 38), then graphed and a one phase decay linear regression performed. The Tau for each population was then determined (solid black line in (B,D,F)) and the 95% confidence interval also plotted (dotted black line in (B,D,F)). Only probes with a total cDNA expression greater than Tau were used in further analysis. Details of Tau thresholds are in Additional files 6 and 11.
