CpG methylation beta values and sample age for the advanced forensic biology lesson

This dataset should be used for the practical of the "Advanced Forensic Biology" lesson. It has been slightly modified from the initial source (see below). It consists of two parts: <strong>1) CpG methylation beta values</strong>: tabulated separated methylation beta values in a file called cpg_methylation_beta_values.tsv. <strong>2) Samples to chronological age </strong>: the relationship between sample identifiers and their chronological age in a tabulated separated file called cpg_methylation_sample_age.tsv. <strong>3) CpG identifier to gene symbol and annotation:</strong> a tabulated separated file containing the relationship between CpG island identifier, the corresponding gene and its functional annotation. cpg_methylation_cpg_to_annotation.tsv <br> <strong>Dataset provenance:</strong> Bocklandt S, Lin W, Sehl ME, Sánchez FJ, Sinsheimer JS, Horvath S, Vilain E.
