+
+**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

+
+**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
