Table 2. Obelisk read counts from paired metagenomic (DNA) and metatranscriptomic (RNA) samples.

Paired metagenomic DNA and metatranscriptomic RNA Kraken2 read counts (Bracken-corrected, see methods) for Lloyd-Price et al. 2019 ²⁰ and Maghini and Dvorak et al. 2023 ⁷⁹ for Obelisks -α and -β. Means taken over donors (aliased as in Table 6) and total read counts also reported. Note that no reads mapping to either Obelisk were found in the DNA datasets, suggesting an RNA-only Obelisk lifestyle. For full Kraken2 and Bracken outputs, see Data Availability.
