Dear colleagues,
I am Diana, and I am working with HMP2 data—specifically, the metagenomics data. My question is: what is the difference between samples with the suffixes _TR and _P and those without them? If I wanted to use the data in taxonomic_profiles_3.tsv.gz to obtain a single sample per person for each stool collection, which samples would be the most appropriate to consider? I was thinking of selecting those without the _P suffix to ensure I have only single-end samples, and then calculating the arithmetic mean for each bacterium across the _TR samples and the standard ones. Could you please clarify?
