EMP - OTU Table

FINALLY FIGURED OUT HOW TO GET OTU TABLE!

1. Remember the EMP Open .biom file was too large (too much memory - crashed Python)
2. Converted format to HDF5 file for easier manipulation
3. Found this convenient python class
4. Which then enables (if biom is installed...) and only if hdf5 file is in correct format

$ biom subset-table -i full_emp_table_hdf5.h5 -a observation -s curto-only-ids.txt -o full_emp_table_curto.biom

$ biom convert -i full_emp_table_curto.biom -o full_emp_table_curto.txt --to_tsv --header-key taxonomy
