WebAug 31, 2024 · In case of bwa-mem, if we assume the matching score is 1, type-3 error is estimated with: 10 / log 10 ⋅ [ log 4 ⋅ ( S 1 − S 2) − log n s u b] where S 1 is the best alignment score, S 2 is the second best and n s u b is the number of suboptimal alignments. Factor log 4 comes from the scoring matrix. Factor 10 / log 10 is the Phred scale. WebBWA trims a read down to argmax_x {\sum_ {i=x+1}^l (INT-q_i)} if q_l things adults should know how to do

WebFeb 11, 2024 · If you are aligning using BWA MEM and have samtools available in your $PATH, it might even be easier to produce interleaved output (since BWA MEM can read interleaved FASTQs) using the samtools fastq command. This would save some work having to group each list of FASTQs into pairs, ensuring they are ordered as expected. WebBut when BWA finds multiple mapping locations it assigns the read randomly to one position. With two references, there are no "properly paired" reads as all reads map to multiple locations, and BWA assigns randomly the primary alignment. The "rescue" you saw was probably random variation.
