    return <<USAGE;
Usage: iterative_cdhit [options]
Iteratively cluster a FASTA file of proteins with CD-hit, lower the threshold each time and extracting core genes (1 per isolate) to another file, and remove them from the input proteins file.

Required arguments:
         -m STR   input FASTA file of protein sequences [_combined_files]

Options: -p INT   number of threads [1]
         -n INT   number of isolates [1]
         -c STR   cd-hit output filename [_clustered]
         -f STR   output filename for filtered sequences [_clustered_filtered.fa]
         -l FLOAT lower bound percentage identity [98.0]
         -u FLOAT upper bound percentage identity [99.0]
         -s FLOAT step size for percentage identity [0.5]
         -v       verbose output to STDOUT
         -h       this help message
