概括
一个新的R包,PIPETS,为细菌3'-end测序数据提供了一种标准化分析方法. 它比现有的方法在不同基因组区域中识别出更多的终止信号,改善了研究人员的数据分析.
科学领域:
- 基因组学就是基因组学.
- 生物信息学是一种生物信息学.
- 分子生物学分子生物学
背景情况:
- 短读测序成本下降,导致基于测序的生物研究的使用增加.
- 缺乏用于细菌3端测序数据的标准化分析方法,这阻碍了可复制的研究.
- 目前的方法往往集中在非编码区域,可能错过了基因内的重要信号.
研究的目的:
- 为细菌3端测序数据开发一种新的,统计学知情的分析方法.
- 为分析这种类型的基因组数据创建一个可访问的R包 (PIPETS).
- 改进跨不同生物体的转录终止信号的识别.
主要方法:
- 开发了PIPETS (Poisson Identification of PEaks from Term-Seq data),这是一个R包,可以在生物导体上获得.
- 采用了基因注释不可知的统计方法.
- 在两种不同细菌物种的数据集上验证了该方法.
主要成果:
- 与现有方法相比,PIPETS在更广泛的基因组环境中发现了显著的3端终结信号.

752.9K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

87.5K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
