构建Pan-genome的方法主要有3种:Iterative、map-to-pan和De novoassembly,Iterative和map-to-pan的方法是通过将短的reads比对到已经注释的基因组上进而鉴定基因的PAVs。然而这种方法对于多拷贝基因的检测是有局限的,且由于作物基因组的高度重复性和SVs的普遍存在,极易出错 (Gan et al., 2011;Zapata et al., 201...

Scalable Reference Genome Assembly from Compressed Pan-Genome Index with SparkHigh-throughput sequencing (HTS) technologies have enabled rapid sequencing of genomes and large-scale genome analytics with massive data sets. Traditionally, genetic variation analyses have been based on the human reference ...

Novel functional sequences uncovered through a bovine multiassembly graph 代码链接 https://github.com/AnimalGenomicsETH/bovine-graphs/tree/main 代码是一个snakemake流程,慢慢看,争取把每个rule都拆解出来 基本思路 使用minigraph做基因组比对,获得一个图基因组,图基因组包含边和节点,节点是序列。然后把每个基因组...
构建pan-genome的方法主要有三种：Iterative、map-to-pan和De novo assembly。Iterative和map-to-pan方法适用于相对低的测序深度下实现pan-genome的研究，而De novo assembly可以提供更准确的pan-genome信息。随着测序技术的发展，特别是长读测序技术和组装方法，实现高质量从头组装的成本降低，有利于未来的De...
In addition, a graph-based pan-genome assembly can efficiently integrate genetic variants of all de novo genomes and identify the major SVs underlying diverse phenotypes20,21,22. In this study, we assemble 32 high-quality genomes of representative A. thaliana ecotypes from across their respective...
Genome assembly Contig genome assembly of the ten accessions was performed from CCS clean reads using the hifiasm92software with parameters settings: “-l 2 --purge-cov 100 --high-het -s 0.01”. For GS and FJ de novo genome assembly was performed to anchor contigs into chromosomes using Hi...
Assembly of diverse Chinese genomes 68个样本:代表了36个少数民族和8个具有语言群体的中国泛基因组联盟核心样本 hifi:28.82X(14.29–60.67×) 9个sample 测了 linked reads; 11个sample测了ONT三代以及hic数据 组装了58个单倍型水平的组装体(图 1a)
Assembly The process of overlapping sequencing reads from many copies of a genome in order to piece together short sequences into longer sequences. Assembly is often performed for a whole genome, particularly when no reference is available for alignment, but it can be performed locally, as well...
