Erratum to: Algorithms Mol Biol (2016) 11:20 DOI 10.1186/s13015-016-0083-7

After publication of the original article [1], the authors noticed errors in Algorithm 2 and the caption of Table 4. In Algorithm 2, the term “rank1(Bl, i − 1) + 1” should be included on line 28 and not line 29. In addition, in the caption of Table 4, the word “BVr” should be replaced by “Br” and the word “BVl” should be replaced by “Bl”. The correct versions of Algorithm 2 and Table 4 are included in this erratum.
