Link for new nr mapping file

User Questions

Hi,

I was wondering where I could find the link to access the latest mapping file for the NR database. I saw a couple of posts discussing this and figured this file is available for download along with Megan7 installer files.

When searching online I couldn’t find any website for downloading the latest Megan or the mapping file. I appreciate it if somebody could provide the link here.

Thanks in advance!

Hi @SowmyaPulapet,

You can download MEGAN7 and the necessary mapping files from the following link: MEGAN7 Download. The full NCBI-nr database can be downloaded from the NCBI FTP site. Please note that the updated mapping files should not be used with MEGAN6.

Hi Megan team,

I was wondering if Megan 7 will provide the LSU and SSU mapping files from Silva database like Megan 6? The current database in silva is 138 whereas the mapping files for the Silva database in Megan 6 is 132.
Thank you
