Load ncbi taxonomy
Where to find it
In the 1.1 release,load_ncbi_taxonomy.pl is installed with other scripts with the distribution and will typically go in /usr/bin or /usr/local/bin.
Command line options
- -H hostname for database [required if -g isn't used]
- -D database name</t> [required if <tt>-g isn't used]
- -g GMOD database profile name (can provide host and DB name) Default: default
- -p phylotree name (optional - defaults to NCBI taxonomy tree. You want to set this if you plan to load more than one tree)
- -i input file - list of taxonomy ids to be stored (optional- without this the entire NCBI taxonomy will be loaded)
- -v verbose output
- -t trial mode. Don't perform any store operations at all. (trial mode cannot test inserting associated data for new terms)
For storing phylonodes a new phylotree will be stored with the name 'NCBI taxonomy tree'. Each organism will get a phylonode id and will be stored in a tmp table, since each phylonode (except for the root) has a parent_phylonode_id, which is an internal foreign key. Next each phylonode will get a left and right indexes, which are calculated by walking down the entire tree structure (see article by Aaron Mackey: http://www.oreillynet.com/pub/a/network/2002/11/27/bioconf.html?page=2). Only after each phylonode will have calculated indexes, the phylonode table will be populated from the tmp table.
