Discrepancy between NucleosomeRatio documentation and implementation

[Rushil-Chakra]

Hello,

I noticed that the documentation on theNucleosomeRatio metric states that monoFrags = fragSize < 2 * nucLength. However, the code calculates w <- trunc(width(fragx)/nucLength) + 1. If we were to have a fragment of size 150, the documentation would lead me to believe that this would be classified as a monoFrag as 150 < (147 * 2). However, the implementation would have trunc(150/147) + 1 = 1 + 1 = 2, meaning this is classified as a diFrag.

Is there any guidance on which of these is the correct definition for the NucleosomeRatio? Or am I missing something and the implementation does indeed match the documentation
