Make.biom for picrust

Hello Patrick and mothur community, I have searched near and far for an explanation of the greengenes mapping tables. I’m assuming the 99, 97 etc indicate the “label”, ie, the cutoff for making OTUs. What I can’t figure out is the meaning of the columns and rows. I suspect it could be similar to a name file, where the number in the first column is the representative OTU and the numbers on the same row are according to greengenes identical OTUs?
many thanks,
Giovanni

Hi there,

I think the first column is the OTU number and the column that follow are the ids of the sequences that belong to that OTU
