Data processing |
The initial pre-processing of the raw methylation was performed in R version 3.3.1. Raw signal intensities were obtained from IDAT-files using the minfi Bioconductor package version 1.21.4 in R version 3.3.1. Each sample was individually normalized by performing a background correction (shifting of the 5% percentile of negative control probe intensities to 0) and a dye-bias correction (scaling the mean of normalization control probe intensities to 10,000) for both color channels. The methylated and unmethylated signals were corrected individually. Subsequently, beta values were calculated from the retransformed intensities using an offset of 100 (as recommended by Illumina). Out of 865,859 probes on the EPIC array, 105,454 probes were masked according to Zhou et al. as well as 16,944 probes on the X and Y chromosomes. In total, 743,461 probes were kept for downstream analysis. The beta values were transformed to M-values with the logit2 function of the minfi package version 1.42.0, R version 4.2.0. processed data file contains: Average Beta
