NAME - Setup a local mirror of the NCBI Taxonomy (or GTDB) database


version 0.211470

USAGE --tax=<dir> [optional arguments]



Path to the directory to be created.



Source database from where to download taxonomy files (either NCBI or GTDB, respectively designated as ncbi and gtdb) [default: ncbi].


Rebuild the binary cache file (cachedb.bin) without re-downloading NCBI (or GTDB) Taxonomy files. This is useful to enable custom .dmp files (e.g., misleading.dmp) that were manually added to the directory [default: no].


[Deprecated] Additionally setup optional mapper file associating taxids to GI numbers for all nucleotide and protein sequences stored in GenBank [default: no].

This file is compiled from two large NCBI archives (1GB and 388 MB as of 12/2014) that can be lengthy to download. Once built, the GI-to-taxid mapper does not occupy a lot of disk space (2 GB as of 12/2014). However, its building process currently requires about 10x more free space.
