ToMMo has constructed the Japanese referenece genome v1 (JRGv1) with a long-read sequencing technology.
On 15 July, 2016, ToMMo released the decoy* assembly to GRCh38, decoyJRG v1, a collection of sequences that are missing from the human reference genome sequence GRCh38 by the Genome Reference Consortium.
You can download decoyJRGv1.fasta from https://jrg.megabank.tohoku.ac.jp/en/.
JRG v1 will be released on summer!
*The decoy sequences are virtual merged sequences that failed to align to GRCh38. They are useful to analysis sequence results.
