Hi, I am Edward and still a student. The curatedmetagenomicsData uses HuMAnNx for functional analysis on microbiome, including mainly pathway abundance and pathway coverage. In HuMAnNx doc, the pathway abundance values seems to be over 1 in the most cases, but just wondering why the values in pathway abundance datasets acquired from curatedmetagenomics are all falling between 0~1. Is there any additional normalization or processing strategies on the data ?

Thanks~
