Hi there,
I tried to merge metaphlan outputs into a table, however I’ve gotten this error. I’m not sure what went wrong.
The script that I input here was: merge_metaphlan_tables.py *.tsv > merged_abundance_table.tsv
The metaphlan version that I was using is: MetaPhlAn version 3.0.13 (27 Jul 2021)
The error was as follows:
merge_metaphlan_tables.py *.tsv > merged_abundance_table.tsvTraceback (most recent call last):

ValueError: Usecols do not match columns, columns expected but not found: [0, 1, 2]
And here’s the input metaphlan table files that I am trying to merge:
metaphlan_taxonomic_profiles_donor.tsv (29.9 KB)
metaphlan_taxonomic_profiles_postFMT.tsv (29.0 KB)
metaphlan_taxonomic_profiles_preFMT.tsv (19.4 KB)
Any help will be much appreciated! Thanks!
Regards,
Kelly
