Software Requirements
- R, get from [CRAN]
- Bioconductor, get from [Bioconductor]
- Bioconductor packages. Install as needed:
- beadarray
- limma
source("http://www.bioconductor.org/biocLite.R")
biocLite("PACKAGE")
Loading Data
- At a minimum you need the Probe Profile data (normally a txt file).
- For all R procedures first change directory to your working directory then next create a new script, and save all executed lines in that script file.
- Load the beadarray library, indictate dataFile (required), sampleSheet (normally a xls or csv file) and control set (Control Probe, normally a txt file)
data = "FinalReport_SampleProbe.txt" controls = "ControlProbe.txt" samplesheet = "Proj_54_12Aug09_WGGEX_SS_name.csv" BSData = readBeadSummaryData(dataFile = data, qcFile= controls, sampleSheet=samplesheet, controlID="TargetID")
