It is common to analyze non-living material samples in metabolomics experiments. For these samples, choose an appropriate name from metagenomes of NCBI Taxonomy (please think excluding metagenome). Here are a few examples.
- food sample: food metagenome
- soil sample: soil metagenome
For some non-living samples, please use names other than metagenomes.
- blank measurement: “blank sample”
- reference compound: “unidentified”
