Hello BioStars community,

I am working with my 16S data and I am having difficulties interpreting the result of make_network and plot_network with default options.

# source('http://bioconductor.org/biocLite.R')
# biocLite('phyloseq')

library('phyloseq')

b <- make_network(a, type="taxa",max.dis=0.5)
plot_network(b,a, type="taxa", label="Genus", color="Phylum")

I see that the default option uses distance="jaccard" and according to vegdist {vegan}, Jaccard index is computed as 2B/(1+B), where B is Bray–Curtis dissimilarity.

Can anyone help me to understand what taxa connection can be interpret?

Thanks
