Krona vs MEGAN for metagenomic data

Question

[CC]

I was wondering if someone could please explain the difference between Krona and MEGAN to me? I realise that you visualise metagenomic data with them, but do they do the same thing?

I guess I'm confused because you can use a blast result file as input for both of them, but you can also use a MEGAN file as input for Krona. So is MEGAN doing something that Krona isn't?

I have blast results for a metagenomic sample, and I want to find a way to visualise all the data and deal with the multiple hits per query. Which program would be the best for this?

Thank you so much for your help, and apologies if this has been answered elsewhere.

Krona tools can visualise the results generated from BLAST or DIAMOND whereas MEGAN is an analysis tool where you can analyse the data as well as visualise it.
