HiC1
An 11-month-old, farmed male Hippocampus erectus was used for the Hi-C analysis. The library was prepared following a standard in situ Hi-C protocol for blood samples, using DpnII (NEB, Ipswich, USA) as the restriction enzyme. A standard circularization step was carried out, followed by DNA nanoballs (DNB) preparation according to the standard protocol of the BGISEQ-500 sequencing platform as described previously. The library was then sequenced with a PE100 strategy using the BGISEQ-500 platform.
