Examples of Read Mapping with Karma and BWA - Genome

Does BWA find chimeric reads? Yes, both BWA-SW and BWA-MEM are able to find chimera. BWA usually reports one alignment for each read but may output two or more alignments if the read/contig is a chimera. I see a read stands out the end of a chromosome and is flagged as unmapped (flag 0x4). What is happening here? Internally BWA concatenates

BWA can be used for : gapped aligning for single-end reads, paired-end mapping and mapping quality. It is composed of three algorithms: (i) BWA-backtrack, for Illumina sequence reads up to 100bp; (ii) BWA-SW for local alignments including long-read support and split alignment and (iii) BWA-MEM, that consists of an aligner for sequence reads

Both algorithms do gapped alignment. BWA can be used to align both single-end and paired end reads to a reference genome or sequence set.

bwa can also handle single-end reads. The only difference is that you would use samse instead of sampe to generate your SAM file: In this case we have two to use. -1 -2 tells bowtie that these are paired end reads (the .fastq), and specifies which one is which.
