The recipe demonstrates the use of different short read aligners.
There substantially many more differences between aligners beyond their "performance" or so-called "accuracy". Equally important is how we can customize the alignments and what additional information is produced in each of the alignments.
The recipe generates SAM alignment files with different algorithms
bowtie2 in both single end and paired-end mode.
- Downloads the 1976 Ebola - Mayinga Reference Genome
- Downloads paired-end sequencing data for the 2014 outbreak
- Generates single-end sequence alignments with
- Generates paired-end sequence alignments with
samtools flagstat on each of the SAM files.
Readers are invited to investiage the SAM files to identify the differences between aligner outputs.
