Consistency in detection of differential expression between quantities of starting RNA

	reference experiment
test experiment	250 ng	100 ng	50 ng
10 ng	0.62/0.04	0.67/0.04	0.69/0.05
50 ng	0.83/0.07	0.88/0.08
100 ng	0.86/0.06

For the numbers of bead-types for which differential expression between UHRR and Brain was detected we report "X/Y" where X is the proportion of bead-types reported for the reference experiment also reported for the test experiment (e.g. a measure sensitivity), and Y is the proportion of bead-types reported by the test experiment that were not reported by the reference experiment (e.g. FDR). So for example, taking 250 ng as a gold-standard, for this detection measure the 100 ng experiment has 86% sensitivity and an FDR of 0.06.
