BlobPlot

Description

BlobPlots are two-dimensional scatter plots, decorated with coverage and GC histograms
Sequences are represented by circles (with diameters proportional to sequence length) in the scatter plot and coloured by taxonomic affiliation
Circles are positioned on the Y-axis in the scatter plot based on the base coverage of the sequence in the coverage library, a proxy for molarity of input DNA in the sequencing reaction
Circles are position on the X-axis based on their GC content, the proportion of G and C bases in the sequence, which can differ substantially between genomes
Coverage and GC histograms are drawn for each taxonomic group, which are weighted by the total span (cumulative length) of sequences occupying each bin
A legend reflects the taxonomic affiliation of sequences and lists count, total span and N50 by taxonomic group
Taxonomic groups can be plotted at any taxonomic rank and colours are selected dynamically from a colour map
The number of taxonomic groups to be plotted can be controlled (--plotgroups, default is ‘7’) and remaining groups are binned into the category ‘others’
