This is a wrapper for KronaTools (krona.sourceforge.net), which creates
interactive charts of hierarchical abundance. Problems can be reported to
ondovb@nbacc.net.

TOOLS:

    - Krona chart
      Creates a Krona chart from tabular BLAST output (which is classified using
      a lowest common ancestor approach), Galaxy taxonomic representations, or
      NCBI taxonomy IDs.

    - Classify BLAST
      Classifies tabular BLAST results as in the above tool, but only outputs
      the classifications (as NCBI taxonomy IDs) instead of the chart. These can
      also be used to create a chart. 

REQUIRED:

    - KronaTools 2.0 or later (krona.sourceforge.net)

INSTALL:

    - Copy krona.xml (and classify_blast.xml if required) to the desired
      tools directory and update tool_conf.xml to include it.

INTRANETS:

    - If the machines accessing your Galaxy server are not connected to the
      internet, you will need to deploy Krona web resources to the Galaxy
      server.  To do this:

      - From the KronaTools directory, run:

        ./deployResources.sh <galaxy>/static/krona
        (where <galaxy> is the directory of the Galaxy installation)
          
      - Uncomment the line of krona.xml that reads:

        -u /static/krona
