Figure 3From: More accurate recombination prediction in HIV-1 using a robust decoding algorithm for HMMsThe position of borders in labellings. The i th border for a labelling λ, b i (λ), is the first position in λ with the label fi+1. The shift in the i th border, between two labellings λ and λ' that share the same footprint f is |b i (λ) - b i (λ')|.Back to article page
