MetaPhlAn Not generating Results

I am using MetaPhlAn 3.0 with the following command. However, it does not generate any results.

metaphlan scaffolds.fasta --input_type fasta -o profiled_metagenome.txt


#clade_name NCBI_tax_id relative_abundance additional_species
UNKNOWN -1 100.0

Hi @sekhwal
Thanks for getting in touch. Could you give us some information about the content of the fasta file you are trying to process using MetaPhlAn?
