The formulae for Dice and Jaccard indices used to assess volumes concordance should read as follows:

$$\begin{array}{l}\mathit{\text{Dice}}\mathit{\text{index}}=\frac{2\times \left({\mathit{VOI}}_{\mathbf{1}}\cap {\mathit{VOI}}_{\mathbf{2}}\right)}{{\mathit{VOI}}_{\mathbf{1}}+{\mathit{VOI}}_{\mathbf{2}}}\\ \mathit{\text{Jaccard}}\mathit{\text{index}}=\frac{{\mathit{VOI}}_{\mathbf{1}}\cap {\mathit{VOI}}_{\mathbf{2}}}{{\mathit{VOI}}_{\mathbf{1}}\cup {\mathit{VOI}}_{\mathbf{2}}}\end{array}$$

Where ∩ and ∪ represent the intersection and the union of two VOIs, respectively.
