Archive description

These data represent metagenomic and metatranscriptomic analyses of human stool samples preserved in DNA Genotek OMR-200 collection kits and Zymo DNA/RNA Shield collection kits, after exposure to a range of collection conditions. Ten donors were analyzed, and collection conditions were replicated in triplicate.

How this project entered the registry

Classified as human gut / stool shotgun DNA metagenome of age unknown by sonnet_x2 with confidence 0.72. Assay shotgun_dna.
