測序深度和覆蓋度(Sequencing depth and coverage)


總是跑數據,卻對數據一無所知,這說不過去吧。

 

看幾篇文章吧

Sequencing depth and coverage: key considerations in genomic analyses(只講二代)

Assembly of large genomes using second-generation sequencing(參考文獻)

Identification of optimum sequencing depth especially for de novo genome assembly of small genomes using next generation sequencing data(二代最佳測序深度:50X)

Large Genome Assembly with PacBio Long Reads(已更新)(純三代最少50X,二三代聯合:任意深度,策略不同)

 

回答幾個問題:

不同的測序(denovo組裝、重測序、轉錄組、外顯子、表觀),各對數據的深度和覆蓋度有什么要求?

二代和三代在測序深度和覆蓋度上的要求有什么不同?

 

four major study designs:

  1. de novo genome sequencing
  2. genome resequencing
  3. transcriptome sequencing
  4. genomic location analyses (for example, chromatin immunoprecipitation followed by sequencing (ChIP–seq) and chromosome conformation capture (3C))

 

參考資料:

Question: de novo sequence assembly with extremely high coverage

 

待續~
