The original version of this Article contained an error in Eq. 2. This equation incorrectly included a 2 in the denominator, and incorrectly read: \(\beta _{{\mathrm{SIM}}} = \frac{{\mathop {\sum}\nolimits_{i < j} {{\mathrm{min}}\left( {b_{ij}, \, b_{ji}} \right)} }}{{2 \cdot \left( {\mathop {\sum}\nolimits_i {S_i \, - \, S_T} } \right) \, + \, \mathop {\sum}\nolimits_{i < j} {{\mathrm{min}}\left( {b_{ij}, \, b_{ji}} \right)} }}\).

The correct form of Eq. 2 is: \(\beta _{{\mathrm{SIM}}} = \frac{{\mathop {\sum}\nolimits_{i < j} {{\mathrm{min}}\left( {b_{ij},\, b_{ji}} \right)} }}{{\left( {\mathop {\sum}\nolimits_i {S_i \, - \, S_T} } \right) \, + \, \mathop {\sum}\nolimits_{i < j} {{\mathrm{min}}\left( {b_{ij}, \, b_{ji}} \right)} }}\)

All the calculations of BSIM are correct and were made following the correct form of Equation 2.
