Correction to: Scientific Reports https://doi.org/10.1038/s41598-018-35033-y, published online 13 November 2018


The original version of this Article contained a typographical error in Equation 1, where the division line in the fraction “\(\frac{n}{N}\)” was omitted.

$$S\left( k \right) = \mathop \sum \limits_{n = 0}^{N - 1} s\left( n \right)e^{\big({ - 2i\pi k_{N}^{n} }\big)}$$

now reads:

$$S\left( k \right) = \mathop \sum \limits_{n = 0}^{N - 1} s\left( n \right)e^{{ - 2i\pi k\frac{n}{N}}}$$

The original Article has been corrected.
