Softwares for statistitical analysis of MetaPhlAn output

Hi community!!! I have profiled shotgun metagenome data with MetaPhlAn. Now, I want to do statistical analysis (e.g. alpha-, beta- diversity comparison, rarefaction graph, boxplots, PCOA, etc) with the output data. Can anyone please suggest me which software can I use? (provided, I don’t know language like R, python, etc.)

Thanks and regards, DC7

Hi,

You might want to try to use STAMP: Statistical analysis of taxonomic and functional profiles.

It is the only GUI software that I know that may help to perform statistical analyses on taxonomic and functional data tables.

Please read the user guide first to see if the software does what you want.

I hope this helps,

António

P.S.: I never use MetaPhlAn, so I don't know which type of output generates and if STAMP can handle this or not.

Thanks sir. It can import MetaPhlAn output. But I'm getting error like this: 

classification: k__Bacteria|p__Firmicutes|c__Bacilli|o__Bacillales|f__Bacillales_unclassified|g__Gemella

error: "Child g__Gemella has an unclassified parent."

Any idea?

Hi,

Not sure. From the error it seems related with the fact that for that particular taxonomic annotation you got something annotated at genus level - g__Gemella -, but not annotated at family level f__Bacillales_unclassified, that is a higher rank just above the genus. This is quite strange, because if you know what is the genus, you should know the family.

I think the program is complaining about that. I guess this is related with the taxonomic database that you've used. Was this database the database recommend by MetaPhlAn? If so I suggest you to contact the developers of MetaPhlAn to try to address this issue.

Yes sir. The database is CHOCOPHLAN v30 which is recommended by MetPhlAn3. I have created a thread regarding this problem in the metaphlan forum as well as in biostars. Thanks
