Hello, I have applied the fix\_relab\_mpa4.py to my profiled.txt data (run with version 4.1.0 and with the unclassified reads tag) to correct the abundances and taxonomy. However, when I then run the merge\_metaphlan\_tables.py it generates an error:

pandas.errors.ParserError: Too many columns specified: expected 5 and found 4

The only thing I noticed after running the fix\_relab\_mpa4.py function is that the UNCLASSIFIED category has disappeared from the corrected files, so I wonder if that has something to do with it.

Thank you
