Determine numerically a threshold for the ranking score
Description
Given a log 10 transformed of the sorted ranking score values (dscore), this function determines numerically a threshold (inflection point) for significance of sequencing value level. User should specify the lower and the upper bounds of the slope region containing the inflection point.
Usage
scoreThr(dscore, deb, fin)Arguments
dscore |
transformed score values obtained using the function rankReads() |
deb |
integer for lower bound of the slope region containing the inflection point. User should perfom a plot to determine this value |
fin |
integer for upper bound of the slope region containing the inflection point. User should perfom a plot to determine this value |
Value
This function returns two values: “pos” and “thr” which are the index or the number of genes with significant values and the score (-log10(score)) threshold
