Blast output against IMG/VR database


#1

I’ve used the MEGAN since Nov 2014 (version 5.6.6).

​- Where can I find a menu to update the old version of MEGAN I have?

  • If I update to a later version of MEGAN, all the databases, such as NCBI and SEED will be updated automatically as well?

  • I blasted my contigs generated from Illumina HiSeq against the IMG/VR database. In this case, should I upload the IMG/VR database along with the blast output to summarize the taxonomic profile?

​Thanks for your assistance in advance.​

Hi,
you should have a ‘Check for updates’ command in Help menu.
If not you can just download the new version on the website:
http://ab.inf.uni-tuebingen.de/data/software/megan6/download/welcome.html

A lot has changed since 2014, so you’d also have download the new mapping files, also on the website. Im not familiar with the IMG/VR database, but if it is a subset of NCBI databses it should work.

In the new MEGAN you’ll find new methods for long read analysis that would also work for the contigs.
