Overall alignment rate低
WebThe first step in the RNA-Seq workflow is to take the FASTQ files received from the sequencing facility and assess the quality of the sequencing reads. The FASTQ file format is the defacto file format for sequence reads generated from next-generation sequencing technologies. This file format evolved from FASTA in that it contains sequence data ... WebThus we get an overall alignment rate of 81.45%: this consists of all the single reads that align at least once (no matter if they are multimappers, if the other pair of the read pair didn’t map as expected or at all). The formula to get this number out of the reported numbers above is: (137241*2+8502*2+8734*2+15029+1800)/ (2*200000) = 81.45% ...
