Particular release of ncbi taxonomy for megan?


#1

Dear Dr. Huson,

I would like to use megan tool blast2lca for various blast ouputs against various databases. What all these databases have in common, is that I used a particular version of ncbi taxonomy and they are all generated with that same particular version.

I would like to ask, if there is a way to generate my own ncbi.map, ncbi.tre etc files from the particular names.dmp and nodes.dmp (or other taxdump files) used in my databases?

I cannot seem to find anything on that topic, but I would really like to do that to be able to use your tool for lca, and profit from the effort that I put in creating those databases.

Thank you very much in advance for your answer,

A

MEGAN uses the files ncbi.tre, ncbi.map and ncbi.info to represent the NCBI tree. This three files are generated by a program called tools/taxdmp2tree that I have just added to the Ultimate Edition of MEGAN V6_12_5. (The UE contains all command line tools that are required to build any of the files used by MEGAN).
