I did my OTU picking with mothur and converted the OTU table to biom with the command
the produced biom file works with a couple of Qiime (1.9.1) scripts as plot ones but I could not make it work with
core_diversity_analyses.py with an error : ValueError: Shape tuple is incompatible with data.
I could not find whether the problem comes from my biom or my mapping file.
I join the files that I think may be useful for anyone wanting to hep me. It may be something stupid but I could not find it after two days and did not find any related post on the forum yet.
I hope someone can help.
Thanks a lot,
