Size distribution (log scale) of the final Ectocarpus sp. scaffolds after 250 instaGRAAL iterations. After filtering, and prior to correction, 27 main scaffolds (red bars) or putative chromosomes were obtained. The dotted green horizontal line represents the proportion of the filtered genome that was not integrated into the main 27 scaffolds and represents less than 0.6% of the initial assembly. Each scaffold presents, after normalization, a high-quality Hi-C profile with features that are typical of eukaryotic genomes (Additional file 1 Fig. S1)
