| Data processing |
Raw signal intensities were obtained from IDAT files using the minfi Bioconductor package v.1.14.036. 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 of the mean of normalization control probe intensities to 10,000) for both colour channels. Subsequently, a correction for the type of material tissue (FFPE or frozen) was performed by fitting univariate, linear models to the log2-transformed intensity values (removeBatchEffect function, limma package v.3.24.15). Beta values were calculated from the retransformed intensities using an offset of 100 (as recommended by Illumina).
Beta values as calculated from the retransformed intensities using an offset of 100 (as recommended by Illumina). Due to the protected nature of this patient data, only the 358365 probes common to both 450k+EPIC platforms and that are not annotated with a SNP (IlluminaHumanMethylation450k.anno.ilmn12.hg19, dbSNP release 147) are included in the table.
