Hi Andreas,
sorry for the delay in replying. I did get your last two emails but it seems the fist one (On Mon, Jul 25, 2016 at 09:45:57PM) never arrived.
Thanks so much for the suggestions. Tin, can you take a look at these two sets of suggestions and update the source code of MetaPhlAn2 accordingly?
Tin can also provide more info about the binary data in db_v20. The files ending with "bt2" are created using a script in the Bowtie2 package (bowtie2-build) using a sequence file Tin can provide (it can also be recovered from the bt2 files with bowtie2-inspect if I remember well).
For the mpa_v20_m200.pkl Tin can also provide the uncompressed python object (or he can provide a couple of lines of code to uncompress it?)
For the LEfSe package I just added the license in the bitbucket repository. For the description, I think you can use the following page:
Does it sound like an appropriate description for the package?
Let me know if you have other questions or if I missed answering to other emails.
thanks so much for your work!
Nicola
