From: Alignment behaviors of short peptides provide a roadmap for functional profiling of metagenomic data
Effect of peptides from “unknown protein-space” on the “frequency-weighted” abundance profiles of proteins from “known space”. Artificial boost in the abundances of KO-families is elucidated using output of ‘Frequency weighted read count’ method when ‘Test case type2.3’ (peptides from unknown space) is added to ‘Selected_4K_KO_Hits’. Red line reflects the true correspondence values
