WebNov 9, 2024 · Respiratory failure associated with COVID-19 has placed focus on the lungs. Here, we present single-nucleus accessible chromatin profiles of 90,980 nuclei and matched single-nucleus transcriptomes of 46,500 nuclei in non-diseased lungs from donors of ~30 weeks gestation,~3 years and ~30 years. Though both Chromap and minimap2 build the minimizer index and extract minimizers from sequences as seeds to map the reads, they use distinct algorithms for seeding and for identifying alignment candidates. Minimap2 applies an expensive chaining procedure on the seeds to generate candidate mapping … See more Double-strand minimizers of reference genomes are collected and indexed using a hash table with minimizer sequences as keys and their sorted … See more We define candidates for a read to be possible mapping start locations on the reference genome, which are estimated by exact minimizer hits (i.e., anchors) between the read … See more For ATAC-seq or scATAC-seq, when a read contains the adapter sequence at the 3′-end, its fragment length can be shorter than the read length. To remove the adapters, for a pair of reads, if a prefix of one read has ≤1 … See more Chromap stores the raw candidates in a cache for frequent reads to avoid repeated candidate generation for reads from peak regions. The cache is a hash table, where the key is a vector of … See more
