+How to prepare NCBI taxonomy for Galaxy Metagenomic Toolkit
+-----------------------------------------------------------
+
+1. run runTest.sh
+   If this script produces NO messages -> everything is OK
+   
+2. run processRaxonomy.sh
+   This script does several things:
+   - downloads taxonomy dump tarball from NCBI ftp site
+   - downloads very large gi2taxId files for nucleotide and protein entries of GenBank
+   - runs a series of 3 python scripts on these files
+   - creates a sqlite database called taxonomy.db (you can use sqlite to explore this database)
+   - this database is used by /tools/metag/tax.py tool to convert gi's into full taxonomic representation
+   
+3. move taxonomy.db into /static/taxonomy/
+
+Taxonomy ranks
+--------------
+
+These scripts consider the following taxonomic ranks:
+
+ 1      root
+ 2      superkingdom
+ 3      kingdom
+ 4      subkingdom
+ 5      superphylum
+ 6      phylum
+ 7      subphylum
+ 8      superclass
+ 9      class
+10      subclass
+11      superorder
+12      order
+13      suborder
+14      superfamily
+15      family
+16      subfamily
+17      tribe
+18      subtribe
+19      genus
+20      subgenus
+21      species
+22      subspecies
