getSCEcoordinates: Get SCE coordinates

In AneuFinder: Analysis of Copy Number Variation in Single-Cell-Sequencing Data

Description

Extracts the coordinates of a sister chromatid exchanges (SCE) from an aneuBiHMM object.

Usage

getSCEcoordinates(model, resolution = c(3, 6), min.segwidth = 2,
  fragments = NULL)

Arguments

model	An aneuBiHMM object.
resolution	An integer vector specifying the resolution at bin level at which to scan for SCE events.
min.segwidth	Segments below this width will be removed before scanning for SCE events.
fragments	A GRanges-class object with read fragments or a file that contains such an object. These reads will be used for fine mapping of the SCE events.

Value

A GRanges-class object containing the SCE coordinates.

Examples

## Get an example BED file with single-cell-sequencing reads
bedfile <- system.file("extdata", "KK150311_VI_07.bam.bed.gz", package="AneuFinderData")
## Bin the BAM file into bin size 1Mp
binned <- binReads(bedfile, assembly='hg19', binsize=1e6,
                  chromosomes=c(1:22,'X','Y'), pairedEndReads=TRUE)
## Fit the Hidden Markov Model
## Find copy-numbers
model <- findCNVs.strandseq(binned[[1]])
## Find sister chromatid exchanges
model$sce <- getSCEcoordinates(model)
print(model$sce)
plot(model)
