DAM methylation profiles derived from three biological replicates fed on daf-2 RNAi (no heat shock) showed a high degree of correlation between replicates. Sequences was identified with methylation peaks in the top 1% of smoothed log2 ratios (log2 ratio > 1.5) and within the gene boundary or 2kb upstream of the translational start. This defined 1135 methylation peaks and 907 associated genes, with a false discovery rate of <5%.

Authors first used a Student t test to select only those genes that were significantly regulated using both the observed standard deviation (local SD) and the global standard deviation compiled from a large number of different DNA microarray experiments (global SD). Authors selected genes that are sex regulated above the 95% confidence level.

All data were analyzed using Stat View J 5.0, with all experimental data checked for assumptions of homogeneity of variance across manipulations using Bartletts test. Once the assumptions were satisfied, the data were analyzed by one-way analysis of variance followed by Dunnetts multiple comparison test. When homogeneity was not evident in the data, we used the nonparametric KruskalWallis test, followed by the MannWhitney U-test with a Bonferroni adjustment. Differences were considered significant at P < 0.05.

Affymetrix TAS software that computed for each probe estimates of fold enrichment (in linear scale) over hybridization with input DNA. At the same time, TAS calculated for each probe a p-value by applying a Wilcoxon signed rank test. A threshold of 2.5 was selected, which corresponds to probe intensities approximately 2.5 times stronger on the ChIP array than on the Input array. Additional TAS threshold parameters were MinRun=180 bp, MaxGap=300 bp. TAS analysis showed that the selected threshold of 2.5 corresponds approximately to a p-value of 0.01.
