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.

The list of sample files (space separated).The wildcard can also be used.
The database of metaphlan3.py.
The output directory.
The marker file in fasta format.
The number of processors are used for the main threads. Default 1.
The number of processors are used for loading samples. Default nprocs_main.
The number of processors are used for aligning and cleaning markers. Default nprocs_main.
The number of processors are used for running raxml. Default nprocs_main.
The number of runs for bootstraping when building the tree. Default 0.
The reference genome file names. They are separated by spaces.
The consensus markers with the rate of N nucleotides greater than this threshold are removed. Default 0.2.
The number of nucleotides will be deleted from each of two ends of a marker. Default 50.
In each sample, the clades with the rate of present markers less than this threshold are removed. Default 0.8.
Only clades present in at least sample_in_clade samples are kept. Default 2.
If the percentage of samples that a marker present in is less than this threshold, that marker is removed. Default 0.8.
If the number of the trailing nucleotide columns in aligned markers with the percentage of gaps greater than gap_in_trailing_col is less than gap_trailing_col_limit, these columns will be removed. Default 0.2.
If the number of the trailing nucleotide columns in aligned markers with the percentage of gaps greater than gap_in_trailing_col is less than gap_trailing_col_limit, these columns will be removed. Default 101.
The internal nucleotide columns in aligned markers with the percentage of gaps greater than gap_in_internal_col will be removed. Default 0.3.
The samples with full sequences from all markers and having the percentage of gaps greater than this threshold will be removed. Default 0.2.
In aligned markers, if the percentage of nucleotide columns containing more than N_count Ns less than this threshold, these columns will be removed. Default 0.8.
In aligned markers, if the percentage of nucleotide columns containing more than N_count Ns less than N_col threshold, these columns will be removed. Default 0.
In each concatenated sequence of a sample, sequential gap positions is a gap group. A gap group with length greater than this threshold is considered as a long gap group. If the ratio between the number of unique positions in all long gap groups and the concatenated sequence length is less than long_gap_percentage, these positions will be removed from all concatenated sequences. Default 2.
Combining this threshold with long_gap_length to removed long gaps. Default 0.8.
The p_value to reject a non-polymorphic site.Default 0.05.
The clades (space separated) for which the script will compute the marker alignments in fasta format and the phylogenetic trees. If a file name is specified, the clade list in that file where each clade name is on a line will be read.Default "automatically identify all clades".
The file name containing the list of considered markers. The other markers will be discarded. Default "None".
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".
The alignment program. Default "muscle".
Set marker_in_clade=0.5, sample_in_marker=0.5, N_in_marker=0.5, gap_in_sample=0.5. Default "False".
Set marker_in_clade=0.2, sample_in_marker=0.2, N_in_marker=0.8, gap_in_sample=0.8. Default "False".
Keep the alignment files of all markers before cleaning step.
Keep the alignment files of all markers before truncating the starting and ending parts, and cleaning step. This is equivalent to --keep_alignment_files --marker_strip_length 0
Save sample2fullfreq to a msgpack file sample2fullfreq.msgpack.
Use multithreading. Default "Use multiprocessing".
