生物信息学是一种生物信息学.
人口遗传学人口遗传学

背景情况:

链接阅读技术使基因组分区和条形码可用于各种应用.
使用链接读取的全基因组组装是计算密集的,不适合大群体.
描述大型内部结构变体 (SVs) 仍然是一个挑战.

研究的目的:

开发一种高效的,基于区域的双倍体组装方法,以准确检测indel SV.
为了降低与基于链接读取的变异检测相关的计算成本.
为了使大规模的人口研究用于SV分析.

主要方法:

区域Indel管道专注于目标地区 (默认50kb),使用条形码读取.
集成了哈普洛类型算法和局部组合,以产生分相双体结合体.
通过对对比连接到参考序列来检测变异.

主要成果:

在基准实验中,RegionIndel与现有的SV呼叫者相比表现优越.
在删除方面获得了74.8%的F1分数,在插入方面获得了61.8%的F1分数 (10x链接阅读).
在删除方面获得了64.3%的F1分数,在插入方面获得了36.7%的F1分数 (stLFR链接阅读).
报告的高基因型精度:83.6% (10x) 和80.8% (stLFR).

结论:

在目标地区,RegionIndel成功实现了双质组合和indel SV检测.
阶段性双倍体结合方便对与SNP和小INDEL相连的INDEL SV进行研究.
该方法适用于高效的大规模人口研究.

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
