Hi Thank you very much for your singleM. I want to know whether singleM result suitable for constructing phylogenetic tree as it produce a relative short sequences? if possible, which gene is better? Thanks

Hi,

I think that just the 60bp or 20aa translations don't hold a lot of signal individually, but can do in aggregate. So the answer to your question depends on what you hope to interpret from the analysis.

Is the idea to compute phylogenetics based metrics like unifrac?

Hi again,

Ah, OK. I'm not sure about that. You could try treating each of the OTUs separately for each OTU table (probably concentrating just on the genes which target both bacteria and archaea - see singlem metapackage --describe), but I don't have a good feeling for how that would work with inferring assembly mechanisms, and in particular how that would compare to doing the same thing with 16S/ITS.

If you wanted to test it one thing you could try is to see what the answers that each provides when applied to some EMP500 samples maybe, where both analyses have been done?
