Analysis of Newcastle disease virus genome assembly at various read depths. Shown are the longest contig produced at each read depth as a fraction of the full genome length. Subsamples up to 200x were generated using digital normalization. Above 200x, additional reads were added using random subsampling (due to issues with high median cutoffs in the kh-mer package). At each subsampling depth, the final velvetg assembly was optimized for maximum contig length based on the “cov_cutoff” parameter
