BridgeRPvalueEvaluation: Calculate Fold-change of RNA half-life and p-value.

In bridger2: Genome-Wide RNA Degradation Analysis Using BRIC-Seq Data

Description

BridgeRPvalueEvaluation calculates the fold-change of RNA half-life and p-value between two conditions.

Usage

BridgeRPvalueEvaluation(inputFile, group = c("Control", "Knockdown"),
  hour = c(0, 1, 2, 4, 8, 12), comparisonFile = c("Control", "Knockdown"),
  inforColumn = 4, CutoffTimePointNumber = 4, calibration = FALSE,
  save = TRUE, outputPrefix = "BridgeR_6")

Arguments

inputFile	The vector of tab-delimited matrix file.
group	The vector of group names.
hour	The vector of time course about BRIC-seq experiment.
comparisonFile	The vector of group names.
inforColumn	The number of information columns.
CutoffTimePointNumber	The number of minimum time points for calc.
calibration	Calibration of RNA half-life.
save	Whether to save the output matrix file.
outputPrefix	The prefix for the name of the output.

Value

data.table object about Fold-change of RNA half-lives, p-value.
