Machine learning-based tools to predict DNA methylation of locus-specific repetitive elements (RE) by learning surrounding genetic and epigenetic information. These tools provide genomewide and single-base resolution of DNA methylation prediction on RE that are difficult to measure directly using array-based or sequencing-based platforms, which enables epigenome-wide association study (EWAS) and differentially methylated region (DMR) analysis on RE.
Start out generating required dataset for prediction using initREMP
.
The datasets include RE information, RE-CpG (i.e. CpGs located in RE region) information,
and gene annotation, which are maintained in a REMParcel
object.
It is recommended to save these generated data to the working directory so they can be used in the future.
Clean Illumina methylation dataset using grooMethy
. This function
can help identify and fix abnormal values and automatically impute missing values, which are
essential for downstream prediction.
Run remp
to predict genome-wide locus specific RE methylation.
Use the built-in accessors and utilities in REMProduct
object to get or
refine the prediction results.
