SNRQualControl: Computing the SNR

In RNAither: Statistical analysis of high-throughput RNAi screens

Description

Computes the signal to noise ratio for all data, per experiment and per plate for a complete dataset file and plots histograms of the results.

Usage

SNRQualControl(dataSetFile, nbLinesHeader, channel, noise, plotTitle, showPlot)

Arguments

dataSetFile	a dataset file generated with generateDatasetFile
nbLinesHeader	typically 3
channel	a character string specifying the name of the column containing the values for computing the SNR, e.g. "SigIntensity"
noise	A character string specifying the name of the column containing the values for computing the SNR, e.g. "Background"
plotTitle	the plot title
showPlot	0 or 1. 1 will open one or several plot windows in the R GUI, 0 will only save the plot(s) without opening windows

Value

Shows histogram plots of the SNR for the whole dataset file, per experiment and per plate and saves them in a pdf file. The name of the file will be the concatenation of the experiment name specified in the header and the function argument plotTitle.

Examples

data(exampleHeader, package="RNAither")
data(exampleDataset, package="RNAither")
saveDataset(header, dataset, "save_testfile1.txt")

SNRQualControl("save_testfile1.txt", 3, "SigIntensity", "Background", "SNR", 1)
