Concatenated SBWT bit vectors

The concatenated bit vectors from the "plain matrix" of the SBWT proposed by Alanko, Puglisi and Vuohtoniemi[1]. The SBWT in question is built based on a set of 17,336,887 Illumina HiSeq 2500 reads of length 502 sampled from the human gut (SRAidentifier ERR5035349) in a study on irritable bowel syndrome and bile acid malabsorption[2] with k-mer size 31.
