The results of metagenomic analysis are a large amount of data, please tell me what is the minimum percentage value that is significant (0.1%, 0.2%, 0.3%....) at the level of phylum, class, order, family, genus?
Oksana Kisil You should look at dinamic changes of different taxons through the season (OK, permafrost is not a case) and on taxons differentiating locations or soil levels. Even low frequency taxons (0.1-0.2%) can be important for certain biological processes.
