How can bisulphite be used to measure DNA methylation levels?
Bisulphite treatment in combination with specially designed genotyping microarrays makes it possible to measure DNA methylation levels at a preselected fraction of Cs throughout the genome. One key advantage of this approach is the (currently) lower per-sample cost compared with whole-genome bisulphite sequencing.
How is DNA methylation level calculated?
Reads with more than one perfect alignment with the reference sequence are discarded (greyed out), and for each CpG in the genomic DNA sequence, the DNA methylation level (bottom) is calculated as the percentage of aligning Cs among all uniquely mapped reads.
How is methylation calculated in qPCR?
To perform it, two pairs of primers are designed; one pair that favours amplification of methylated and another one of unmethylated DNA. Two qPCR reactions are performed for each sample, and relative methylation is calculated based on the difference of their Ct values.
How can a Bayesian network be used to determine DNA methylation levels?
Bayesian networks have been used for inferring absolute DNA methylation levels for single CpGs from the complex fragment distributions 62, and a bioinformatic analysis pipeline has been described for processing data obtained with the HELP–seq assay 63.
Description
The function calculates differential methylation statistics between two groups of samples. The function uses either logistic regression testor Fisher's Exact test to calculate differential methylation. See the rest of the help page and references for detailed explanation on statistics. rdrr.io
Value
a methylDiffobject containing the differential methylation statistics and locations for regions or bases rdrr.io
Details
Covariates can be included in the analysis. The function will then try to separate the influence of the covariates from the treatment effect via a linear model. The Chisq-test is used per default only when no overdispersion correction isapplied.If overdispersion correction is applied, the function automatically switches to the F-test. The Chisq-tes
