Web--end-to-end entire read must align; no clipping (on) #比对是将整个 read和参考序列进行比对. 该模式 --ma的值为 0,与 --local 是非彼即此关系,默认选择。 --local local … WebBowtie 2 supports a "local" alignment mode, which doesn't require that reads align end-to-end. This produces alignments that might be "trimmed" (or "soft clipped") at one or both extremes in a way that optimizes alignment score. Bowtie 2 also supports an "end-to-end" alignment mode which, like Bowtie 1, requires that the read align entirely.
WebHere is the relevant bowtie2 manual entry: End-to-end alignment score example. ... Local alignment score example. A mismatched base at a high-quality position in the read receives a penalty of -6 by default. A length-2 read gap receives a penalty of -11 by default (-5 for the gap open, -3 for the first extension, -3 for the second extension). ... WebOct 12, 2024 · bowtie2相关术语解读 1. 比对模式. bowtie2里面有两种比对模式:end-to-end, local。前者在比对时要read的首尾比对上,中间没有比对上的作为gap进行罚分.而local比对模式在比对时,优先保证read内部而非两端的比对,就比对效果上看,local模式下的read两端没有比对上,类似切了两端,所以又称为soft clipped。
