Given absolute abundance estimate taxonomic relationships

Question

[Edmond]

Hello !

I have two sets of data of gut microbiome. I only have the absolute abundance for the genus and the phylum. I do not have the sequences (16 r seq)

I would like to relate the taxonomical units, i.e I have already the names of the genus and the phylum but how these two are related I do not know

Given the fact that I only have the absolute abundance across 46 subjects, does any one knows how to obtain this phylogenetic tree ? Or with another tool ?

Thank you
