Metaquast largest contig by species identical for most species in the metagenomic assembly

Question

[Matteo Schiavinato]

Hi everyone,

I recently generated a metagenomic assembly with Canu. I am now assessing its content with metaquast. Hence, I'm asking the metaquast experts. In the report there is the "largest contig" line, which shows the largest assembled contig in the assembly. Expanding it with the "+", I can see the largest contig for each detected species.

In my case, there are ~20 species but the problem is that almost each of them shows the same value as "largest contig". In other words, I am afraid that I have a very large contig which is the cross-assembly of all these species.

Am I assuming right?
