Updated mapping file?


#1

Hi, would it be possible to get an updated “Protein accession to NCBI-taxonomy mapping file”?

Hi,

the newest mapping files are available on the website:
http://ab.inf.uni-tuebingen.de/data/software/megan6/download/welcome.html

Do you mean the June2018 lacks some important information?

Regards,
Ania

Hi Ania, yes I have the June one but as new sequences are put in the databases in principle every day the file gets out of date rather fast. For example, I work with viral metagenomics and did diamond blastx on a dataset recently and using the june mapping files some viral hits are placed in the “Not assigned” with an “?” which I think is due to the mapping file not being up to date.

I have just created the latest mapping files, they are available on the MEGAN6 download page.
Also, I have updated the NCBI taxonomy used by MEGAN, it is available in release 6.13.0
