This class is used in the methylPipe library to point to a TABIX compressed file containing base-resolution DNA-methylation data and reference genome sequence
Objects can be created by calls of the form
or using the function BSdata(file, uncov, org) whose arguments are
described in the next section Slots.
Object of class
"character" : the TABIX
compressed file containing base-resolution DNA-methylation data.
This file can be generated through the
function, and it must contain the following columns:
chromosome assignment (in the form chr1, chr2...),
genomic position (positive integer),
strand (either - or +),
methylation sequence context (either CG, CHG or CHH),
number (>0) of sequencing reads with C calls at that genomic position,
number of sequencing reads with T calls at that genomic position,
binomial pvalue (-10*log10(pvalue)) for calling a mC at that position.
Object of class GRanges : this
GRanges object consists of the list of genomic regions with
sequencing coverage information; this information is used to distinguish
which methylation sites are unmethylated, but covered, from those
that are missing data since they have no sequencing coverage. This
object is automatically generated by the
function while processing aligned files generated from the aligner.
