BPMAPCelParser: BPMAP and CEL files Reader

Description

One-step reading of BPMAP and CEL files, using Fusion SDK and affxparser.

Usage

BPMAPCelParser(BPMAPFileName, CelFileNames, genomeName=NULL, verbose=FALSE,groupName="",seqName="")

Arguments

BPMAPFileName

String containing the full filename of the BPMAP file.

CelFileNames

Vector of strings containing full filenames of CEL files. i.e. c("F1.CEL", "F2.CEL"

genomeName

String containing the genome name used.

groupName

String containing the group of genome name used.

seqName

String containing the group of sequence name (e.g. chromosome) used.

verbose

If verbose is selected, the progress and additional information will be displayed while the function is running

Value

An object of class tilingSet.

Details

This function returns an object of class tilingSet containing all necessary information: probe sequences, genomic positions, chromosomes as well as the probe intensities.
