概括

选择正确的长读组装器和预处理是准确微生物基因组组装的关键. 下一篇:Denovo和NECAT提供近乎完整的,单一的结果,而另一些则提供更快的草稿或平衡的性能.

科学领域:

微生物基因组学微生物基因组学
生物信息学是一种生物信息学.
测序技术的技术测序技术.

背景情况:

基因组组装对微生物基因组学至关重要,影响下游分析.
长读测序增强了基因组重建,但组装器选择至关重要.
装配质量在很大程度上取决于装配器和预处理步骤.

研究的目的:

为了对微生物基因组学进行11个长时间读取的汇编器进行基准测试.
根据运行时间,连续性和完整性来评估汇编器性能.
评估预加工方法对组装质量的影响.

主要方法:

进行了11个长读组装器的基准测试 (Canu,Flye,HINGE,Miniasm,NECAT,NextDenovo,Raven,Shasta,SmartDenovo,wtdbg2,Unicycler).这些组装器的产品包括:
标准化计算资源被用于评估.
组件使用运行时间,连续性指标 (N50,长度,计数),GC内容和基准测试通用单拷贝正统 (BUSCO) 进行了评估,以确定完整性.

主要成果:

下一篇丹诺和NECAT始终生产近乎完整的单一连接组件,错误组装率低.
弗莱平衡了准确性和连续性;卡努准确但碎片化;Unicycler生产了圆形组件.
超快的工具 (Miniasm,Shasta) 需要抛光;HINGE和wtdbg2的性能不佳.
预处理 (过,修剪,校正) 显著影响了组装质量和完整性.

结论:

组装器选择和预处理对于准确,连续和高效的微生物基因组组装至关重要.
下一篇为高质量,完整的组件推Denovo和NECAT.
没有单一的组装器是普遍最佳的;管道选择取决于特定的基因组目标.

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.
