<i>K-mer</i> frequency calculated at coding, non-coding and repeated sequences in each assembly filtered for scaffolds larger than 50 kb.

Non-coding enrichment calculated as the ratio of the k-mer frequency at non-coding over its frequency at coding sequences. Repeat enrichment calculated as the ratio of the k-mer frequency at repeats over its frequency at non-coding sequences. For each k-mer we report the proportion of the 1,239 genome assemblies showing noncoding or repeat enrichment larger than 2. (XLSX)
