Hi everyone,

I plan to use 16S sequences of some specific microorganisms from IMG/Mer to create a database. I can download the whole genome of a species but still cannot find where to download 16S sequences or how to find 16S sequences from the downloaded files.

For example, for one microorganism, I got several files such as .fna, .genes.fna, .genes.faa, .intergenic.fna ,.gff, .cog.tab.txt, .kog.tab.txt, .pfam.tab.txt, .tigrfam.tab.txt, .ipr.tab.txt, .ko.txt, .signalp.txt.

From .genes.faa file, I could find some genes like 16S rRNA (cytidine1402-2'-O)-methyltransferase, 16S rRNA processing protein RimM, small subunit ribosomal protein S16, but it is probably not 16S gene.

Could you please suggest to me how to find this and especially good for downloading data of a large number of species? or how to find it from the attached file?

Thank you for spending your time.

Have a nice day.
