Scientific Reports 5: Article number: 9519; published online: 27 April 2015; updated: 02 September 2015.

In the Supplementary Information file originally published with this Article, there are typographical errors.

In the section under ‘Convergence’,

“In order to evaluate such convergence, we fit the last time steps of the evolution to a linear trend, using the QR decomposition method”

should read:

“In order to evaluate such convergence, we fit the last time steps of the evolution to a linear trend, using the QR decomposition method”

In the section under ‘Analysis of Fluctuations’,

“For each one of the I repetitions of the experiment we fit a linear model to the final time steps of the simulation, .”

should read:

“For each one of the I repetitions of the experiment we fit a linear model to the final time steps of the simulation, .”

Lastly, Equation (2.1),

should read:

These errors have been corrected in the Supplementary Information that now accompanies the Article.
