Biom add-metadata problem

Hi!

Yes, I saw it, and I followed those steps exactly. This is not my first time with this action but this time doesn’t work. Is it possible that the problem would be that I filtered the feature table? I mean, I have in my feature table two sample types and I filter the table just for working with one and the I used rarefied command to normalize my table. Then I tried to export to biom for using in R and was my problem.

In case this would be the problem, how can I solve? Because I cannot find any command to filter the taxonomy just for the OTUIDs that you have in your selected subsample data. Due to this, my taxonomy file has more entrances than my feature table.

Thanks in advance!
