Function

Index NCBI taxonomy using b+tree indices

Description

dbxflat indexes NCBI taxonomy files, and builds EMBOSS B+tree format index files.

These indexes allow access of flat files larger than 2Gb.

Usage

Here is a sample session with dbxtax

Input file format

dbxtax reads and indexes the NCBI taxonomy nodes.dmp, names.dmp, division.dmp, gencode.dmp,and merged.dmp files.

Output file format

dbxtax creates one summary file for the database and two files for each field indexed.
