merge .biom files

[Giffredo]

Hi,

I would like to ask you if it is possible to merge .biom file.
Maybe it is not possible directly but starting from the bam files?

I tried the code

merge_otu_tables.py -i otu_table1.biom,otu_table2.biom -o merged.biom

In this case I merged 5 files biom and I obtained 5 file merged.biom and it is not possible to create the summarize table by

summarize_taxa_through_plots.py

Someone has a solution for me?

Thanks
