DESCRIPTION

       Metaphlan2_strainer  is  a computational tool for tracking individual strains across large
       set of samples. The input of metaphlan2_strainer is a set of metagenomic samples  and  the
       output is a set of phylogenetic.  For each sample, metaphlan2_strainer extracts the strain
       of a specific species by merging and concatenating all reads mapped against  that  species
       markers in the MetaPhlAn2 database.

       --gap_in_internal_col GAP_IN_INTERNAL_COL
              The internal nucleotide columns in aligned markers  with  the  percentage  of  gaps
              greater than gap_in_internal_col will be removed. Default 0.3.

       --gap_in_sample GAP_IN_SAMPLE
              The  samples with full sequences from all markers and having the percentage of gaps
              greater than this threshold will be removed. Default 0.2.

       --N_col N_COL
              In aligned markers, if the percentage of nucleotide columns  containing  more  than

       --marker_list_fn MARKER_LIST_FN
              The  file name containing the list of considered markers. The other markers will be
              discarded. Default "None".

       --print_clades_only
              Only print the potential clades and stop without building any tree. This option  is
              useful  when  you want to check quickly all possible clades and rerun only for some
              specific ones. Default "False".

       --alignment_program {muscle,mafft}
              The alignment program. Default "muscle".

              Keep the alignment files of all markers before cleaning step.

       --keep_full_alignment_files

              parts,   and   cleaning   step.   This   is  equivalent  to  --keep_alignment_files
              --marker_strip_length 0

              Save sample2fullfreq to a msgpack file sample2fullfreq.msgpack.
