Fig. 1: Kraken2 classification of metagenomic and metatranscriptomic reads.

Metagenomics (A) and metatranscriptomics (B) reads classified at the genus level using Kraken2 across different dietary groups. Only the top 10 most abundant taxa are shown, while the remaining taxa are grouped as other. Reads that couldn’t be assigned any taxonomy are classified as unassigned. CG Control group, IN1 1% inulin, IN4 4% inulin, CE1 1% ARBOCEL, CE4 4% ARBOCEL.
