例如多重比对的 reads 分配问题,将 reads split 切割之后的比对,包括 spliced 与 clipped reads 的比对。 二、clipped alignment clipped alignment:切出两侧比对不上的,read 只有中间部分能比对上,两侧在比对过程中被忽略 三、soft-clipped 和 hard-clipped clipped alignment 分为 soft-clipped 和 hard-clipped,在 SAM/BAM 的 CIGAR 列分别用“S”和“H”表示,比对完将 clipped 序列继续保留输出的,称为 soft-clipped,直接切掉不保留的称为 had-clipped。

截断(或“soft clipping”)reads的clipped boundaries代表潜在的融合断点。 R1和R2有四种可能的取向,然而,只有上图D所示的1a和2a病例可以产生有效的融合,因为它们的reads具有面向相反方向的soft-clipped sequences。 最后,为了在read comparison和断点调整后验证候选融合,FACTERA使用BLASTN将所有 soft-clipped a和未映射的reads与每个候选融合序列(在断点上下填充500 bp reads.blastreads.fa = used to build blast database of soft-clipped, improperly paired, and unmapped followed by not clipped; NC, vice versaOrder2Same as Order1, but for breakpoint 2Break_depthNumber of
