Fig. 2 A chromosome-level genome assembly of the striped catfish. (a)Contig contact matrix of the assembled genome. The color depth represents the density of Hi-C interactions. (b) A Circos atlas of the chromosomal genome for the striped catfish. From outside to inside rings include: (I) chromosomes (Mb in length), (II) distribution of gene density within 1-Mb non-overlapping windows, and (III) distribution of genomic GC content in 100-kb non-overlapping windows. The internal syntenic blocks are connected with lines.
