**What it does**

Creates taxonomic classifications for each query in BLAST results by finding the lowest common ancestor (or by picking randomly, if specified) of "best" hits (as determined by e-value factor above). Requires a KronaTools_ installation (2.0 or higher) with taxonomy downloaded.

 .. _KronaTools: http://krona.sourceforge.net

**Input**

Tabular BLAST results containing gi numbers. If comment lines are present, queries with no hits will be assigned to taxon -1 (consistent with MEGAN).

Example input (BLAST)::

  1      2                            3      4    5  6  7  8    9        10       11     12
  read1  gi|211853080|gb|EQ846228.1|  97.33  150  1  3  6  154  9518999  9519146  5e-64  252
  read2  gi|211853080|gb|EQ846228.1|  96.69  151  0  5  6  154  9496147  9496294  2e-62  246

**Output**

The output is a list of query IDs (or counts, if **summarize** is specified) followed by NCBI taxonomy IDs and scores. This can be used to create a Krona chart by specifying "Taxonomy ID list" as the **input type**. If the output is summarized, the **summarized** option must also be specified when creating the chart.

Example output (default)::

  1 (query ID)  2 (tax ID)  3 (score)
  read1         9606        94.34
  read2         9616        32.17

Example output (summarized)::

  1 (count)  2 (tax ID)  3 (score)
  243        9606        94.34
  17         9616        32.17
