WebExercise: How many of the chrI:1000-2000 alignments are from properly paired mapped reads? Properly paired reads have the 0x2 flag set (1). All our reads also have the 0x1 flag set because they are paired-end reads. Mapped reads will have the 0x4 flag cleared (0), and properly paired mapped reads will have the 0x4 flag cleared (0) as well (mate ... WebOct 11, 2024 · To get stats on the alignment, I used samtools flagstat. For several of my samples, the alignment went great (90% mapped, 80% properly paired). However, for a couple of my samples, the properly paired percentage was well below 1%.
