Thank you for this tutorial. I am also trying to get Bugbase compatible biom table, but when I am using the following command "echo -e "#OTUID\ttaxonomy" | cat - 97_otu_taxonomy.txt > 97_otu_taxonomy.txt", it just run forever, and there is no resultant file. Can you please let know what I am missing?
Can you describe what you mean by running forever?
This command is simply replacing the original 97_otu_taxonomy.txt with the added new headers. So you won't see a new file, though perhaps that is not an ideal approach on my end. Regardless, it should take no time at all. Type head 97_otu_taxonomy.txt, if you see #OTUID and taxonomy in the first row then it has worked properly and you can move on.
