FRIP
Fraction of Reads in Peaks, a value of greater than or equal to 0.01 is considered good.
NSC
Normalized Strand Coefficient, The normalized ratio between the fragment-length cross-correlation peak and the background cross-correlation. A value of greater than or equal to 1.05 is considered good.
RSC
Relative Strand Correlation, ratio between the fragment-length peak and the read-length peak. A value of greater than or equal to 0.8 is considered good.
Complexity
This is computed on a sampling of the reads if more than 10M, using Georgi's method. A value greater than or equal to 0.80 is considered good.
