Hi,
I'd like to get the following information about the genomes available at ftp://ftp.ncbi.nih.gov/genomes/Bacteria/
For each taxonomic rank r (species, genus, etc.) and for each taxid t at rank r, I'd like to know how many organisms have t as ancestor. Actually, in the end I need just this aggregated information: for each feasible feasible n, I'd like to obtain the number of NCBI taxid at rank r having n organisms as descendent in the tree.
With the term "organism", I refer to a complete genome contained in the repository above - that is one for each subfolder. In this way, I will also to take into account when there are two or more organisms whose genome is available and are associated to the same species.
I hope my terminology was not too bad...
Thanks in advance!
