A nice plot to see scaling factors used for RNA-seq and 4sU-seq libraries
Description
A nice plot to see scaling factors used for RNA-seq and 4sU-seq libraries
This method generates a plot that immediately shows the scaling factors used to scale
RNA- and 4sU-seq libraries and the possible relations between them. The ratio between the RNA- and the
4sU-seq scaling can be in fact considered as a yield of the synthesis within the cells.
Usage

For some genes only synthesis and degradation will be evaluated because they have zero valued features in more than 2/3 of the time points in their intronic features: 333193; 94067; 230866; 68961; 100042464; 667250; 59288; 100038734; 100113398; 100040591
Some genes have only exons RPKMs, on them only synthesis and degradation will be evaluated.
