新一代测序方法 能得到更深的测序深度

  • Read:A short DNA fragment which is read out by sequencer

    由测序仪读出的一个短的DNA片段

  • Quality:Given p = the probability of a base calling is wrong(碱基调用错误的概率), its Quality Score can be written as

    Untitled Untitled

    质量分数小于20,错误率大于0.01的碱基,认为是不可靠的,如果这样的碱基超过reads的20%,就考虑将此条reads丢弃掉

  • Paired-End Reads 同时对序列两端较长的片段进行测序

  • 新一代测序的出现,促进了很多的相关领域的研究
