This is a small experiment on the alignment of ~50bp INDELs. The query sequences are shown in 0.01.fq below, where seq_ori is a 204bp sequence extracted from the human reference genome, seq_del54 contains a 54bp deletion in the middle, seq_del84 contains a 84bp deletion in a 120bp read, and seq_ins40 contains a 40bp insertion in a 140bp read. These four short sequences were mapped to the human reference genome with Bowtie2, BWA-MEM, LAST, Novoalign, SNAP and Stampy with default settings. Non-default scoring functions were also tested for Bowtie2 (--rdg 5,1 --rfg 5,1), BWA-MEM (-A2 -E1) and LAST (-r2 -q4). The output by various mappers/settings can be found in this gist. The following table gives my summary:

Mapper	Setting	-84bp	-54bp	+40bp
BBMAP	default	Yes	Yes	Yes
Bowtie2	default	No	No	No
Bowtie2	--rdg 5,1 --rfg 5,1	as insertion	as insertion	Yes
BWA-MEM	default	as split	Yes	Yes
BWA-MEM	-A2 -E1	Yes	Yes	Yes
LAST	default	as split	as split

Steps:

1. Follow steps 1-5 in the first link above to acquire access_token. This will take a while, but you only need to do this once. Never share this token!!
2. Find the file you want to download. Copy the link, which looks something like: https://basespace.illumina.com/sample/9804795/files/tree/NA12878-L1_S1_L001_R1_001.fastq.gz?id=515013503. The "id" is the unique file identifier.
3. Download the file with: wget -O filename 'https://api.basespace.illumina.com/v1pre3/files/{id}/content?access_token={token}', where {token} is from step 1 and {id} from step 2.
