Description GLSS-HF-1E83-R1-01M-EPC-362E33
Data processing The raw DNA methylation intensity data files (IDAT) were processed with the minfi package. We performed noob (Normal-exponential convolution using out-of-band probes) background correction and dye bias correction using the minfi package (v 1.36.0). The DNA methylation value for each locus is presented as a beta (β) value (β = (M/(M+U)) in which M and U indicate the mean methylated and unmethylated signal intensities for each locus, respectively. β-values range from zero to one, with scores of zero indicating no DNA methylation and scores of one indicating complete DNA methylation. A detection p-value also accompanies each data point and compares the signal intensity difference between the analytical probes and a set of negative control probes on the array. Any data point with a corresponding p-value greater than 1E-4 is deemed not to be statistically significantly different from background and was thus masked as “NA”.
