Qiime 2 Biom File format


#1

I have been trying to import a BIOM file output from QIIME 2 into MEGAN and had no luck. I understand the OTU IDs are in the first column (when converted to TSV) and they can be in the following format,

k__Bacteria;p__Firmicutes;c__Clostridia;o__Clostridiales;f__Ruminococcaceae;g__Faecalibacterium;s__prausnitzii

It is also my understanding that the BIOM file from QIIME 1 had the Greengenes IDs in the first column. So can MEGAN read Greengenes IDs to interpret taxonomy and do I also need to format my ouput from QIIME2 to have greengenes IDs just like Qiime1 ?
