| Description |
sperm DNA methylation
Processed_methylation_data_matrix_SEEDS.RData
|
| Data processing |
Sperm DNA methylation was assessed using Illumina's EPIC Infinium Methylation Beadchip. Raw idat files were imported into R and within-array normalization and dye-bias equalization of Type I and Type II probes was performed using normal-exponential convolution method (Noob) via minfi package. Batch effects were corrected with the ComBat function in the sva package while cross-hybridizing probes were removed using the DMRcate package. probes with detection pvalue >0.01 were also exluced prior to downstream analysis.
Processed matrix contains the NOOB-normalized beta values representing the percent CpG methylation for all the CpGs that passed the preprocessing method.
