BridgeRCore {bridger2}

BridgeR basic function for calculating RNA half-life from BRIC-seq data

Description

BridgeRCore is a basic function for calculating RNA half-life BRIC-seq data and a wrapper of the other individual bridger2 functions.

Usage

BridgeRCore(inputFile, inforColumn = 4, group = c("Control", "Knockdown"),
  hour = c(0, 1, 2, 4, 8, 12), RPKMcutoff = 0.1, cutoffBelow = 0.1,
  YMin = -2, YMax = 2, downsamplingFig = 0.2, makeFig = FALSE,
  cutoffQuantile = 0.975, inforHKGenesRow = "symbol", HKGenes = c("GAPDH",
  "PGK1", "PPIA", "ENO1", "ATP5B", "ALDOA"), CutoffTimePointNumber = 4,
  R2_criteria = 0.9, TimePointRemoval1 = c(1, 2), TimePointRemoval2 = c(8,
  12), ThresholdHalfLife1 = 3, ThresholdHalfLife2 = 12, save = TRUE,
  outputPrefix = "BridgeR", normalization = "default", method = "default")

hour

The vector of time course about BRIC-seq experiment.

RPKMcutoff

Cutoff value of RPKM at 0hr.

cutoffBelow

Cutoff value of RPKM at all time points.

YMin

Y-axis min.

YMax

Y-axis max.

downsamplingFig

the factor for downsampling.

TimePointRemoval2

The candicate_2 of time point removal.

ThresholdHalfLife1

The cutoff of TimePointRemoval1.

ThresholdHalfLife2

The cutoff of TimePointRemoval2.

save

Whether to save the output matrix file.

outputPrefix

The prefix for the name of the output.

normalization

Value

data.table object including RNA half-life, R2 and the selected fitting model.

Examples

halflife_table <- BridgeRCore(RNA_halflife_comparison[1:30,],
                              save = FALSE)
