This function launches the segmentation of allele B fraction only for heterozygous SNPs.
segFracBSignal(
dataSetName,

chromosome = 1:22,
Rho = NULL,
listOfFiles = NULL,
savePlot = TRUE,
verbose = TRUE
)
The name of the data-set folder (it must correspond to a folder name in rawData folder.).
Only in the case of normal-tumor study. A csv file or a data.frame containing the mapping between normal and tumor files. The first column contains the name of normal files and the second the names of associated tumor files.
A vector with the chromosomes to be segmented.
Vector containing all the penalization values to test for the segmentation. If no values are provided, default values will be used.
A vector containing the names of the files in dataSetName folder for which the allele B profile is segmented (default is all the files).
if TRUE, graphics of the segmented allele B profile will be saved in the figures/dataSetName/segmentation/fracB folder. (default=TRUE).
if TRUE print some informations
a data.frame where each row correspond to a different segment with columns :
The name of the signal.
A vector of the same size as copynumber containing the chromosome number.
The starting position of a segment.
The ending position of a segment.
The number of probes in the segment.
Means of the segment.
