The human genome is arranged in 46 chromosomes. The longest is ~250 Mb (~2^28). While a Hilbert curve layout of a single chromosome tends to be informative, there is no obvious meaning in treating the complete human genome as a single 3 Gb linear sequence. Wolfgang On 10/03/2017 21:54,

Two replies: 1. Downsampling? In case you want to use the Hilbert curve for visualisation, please note that you will need a graphics device with resolution 65536 x 65536 to display it. Many people have smaller screens, so binning the genome (e.g. into bins of 10x10=100nt) could be a practical
