test.corr: Statistical test to find a putative transcription start (or end) point.
Description
Test the correlation coefficient between a segment of coverage depth and a vector of 100 integers modeling
a simple shape of sharp increases (or decreases) in transcription: x =???[0..0,1..1] (or x =???[1..1,0..0]).
Usage
test.corr(x, sharpInc = 1, cutCorr = 0.7, cutPVal = 1e-07, flag = 0)
Arguments
x
Segment of coverage depth.
sharpInc
Default value is 1.
cutCorr
Cutoff value for the correlation coefficient. Default values is 0.7.
cutPVal
Cutoff value for the p-value. Default values is 0.0000001.
flag
Indicate weather the correlation test is for a start- or end-point in transcription. Default values is 0 (start-point).
