**What it does**

When performing metagenomic analyses it is often necessary to identify sequence reads corresponding to a particular taxonomic group, or, in other words, diagnostic of a particular taxonomic rank. This utility performs this analysis. It takes data generated by *Taxonomy manipulation->Fetch Taxonomic Ranks* as input and outputs either a list of sequence reads unique to a particular taxonomic rank, or a list of taxonomic ranks and the count of unique reads corresponding to each rank. 

------

**Example**

Suppose the *Taxonomy manipulation->Fetch Taxonomic Ranks* generated the following taxonomy representation::

    read1 2      root Eukaryota Metazoa n n Chordata   Craniata Gnathostomata Mammalia n        Laurasiatheria   n           Ruminantia  n             Bovidae     Bovinae      n          n          Bos        n Bos taurus        n
    read2 12585	 root Eukaryota Metazoa n n Chordata   Craniata Gnathostomata Mammalia n        Euarchontoglires Primates	 Haplorrhini Hominoidea    Hominidae   n            n          n          Homo       n Homo sapiens      n 
    read1 58615  root Eukaryota Metazoa n n Arthropoda n        Hexapoda      Insecta  Neoptera Amphiesmenoptera Lepidoptera Glossata    Papilionoidea Nymphalidae Nymphalinae  Melitaeini Phyciodina Anthanassa n Anthanassa otanes n 
    read3 56785	 root Eukaryota Metazoa n n Chordata   Craniata Gnathostomata Mammalia n        Euarchontoglires Primates	 Haplorrhini Hominoidea    Hominidae   n            n          n          Homo       n Homo sapiens      n   

Running this tool with the following parameters:

  * *Select column with sequence id* set to **c1**
  * *Select taxonomic ranks* with **order**, and **genus** checked
  * *Output format* set to **Diagnostic read list**
  
will return::

    read2 Primates order
    read3 Primates order
    read2 Homo     genus
    read3 Homo     genus
    
Changing *Output format* set to **Number of diagnostic reads per taxonomic rank** will produce::

    Primates 2       order
    Homo     2       genus
    
.. class:: infomark

Note that **read1** is omitted because it is non-unique: it hits Mammals and Insects at the same time.    

--------

.. class:: warningmark

This tool omits "**n**" corresponding to ranks missing from NCBI taxonomy. In the above example *Home sapiens* contains the order name (Primates) while *Bos taurus* does not.
