MetaEuk predictions on Tara Oceans contigs. MetaEuk was run on over 1.3 million contigs assembled from Tara Oceans metagenomic reads against a reference database of ~88 million protein profiles. a The number of MetaEuk predictions per contig increases with its length. Horizontal lines mark contig length quartiles. b Most (76%) MetaEuk predictions had a single putative exon. The absolute number of predictions is indicated above each bar. c Single-exon predictions tend to have longer putative exons than multi-exon predictions
