The accessible chromatin regions were enriched in regulatory elements in human genome and many genetic variations associated with human diseases were identified within them.1 Single-cell assay for transposase-accessible chromatin using sequencing (scATAC-seq) on the next-generation sequencing (NGS) platform is a well-established method to detect open chromatin regions within an individual cell.2 However, there remain challenges in detection of large-scale structural variations (SVs, including insertions, deletions, duplications, inversions and translocations) and haplotype phasing from scATAC-seq data, which can be well resolved by third-generation sequencing (TGS) platform-based single-molecule long-read sequencing. To integrate advantages of long-read sequencing into scATAC-seq, we developed single-cell assay for transposase‐accessible chromatin on Nanopore sequencing platform (scNanoATAC-seq), a plate-based scATAC-seq method suitable for TGS platform (Supplementary information, Fig. S1).
