Retraction of: Scientific Reports https://doi.org/10.1038/srep45608, published online 13 April 2017


Editors have retracted this Article.


After publication of this paper concerns were raised about unusually high level of similarity in the background noise for two different samples in Figure 3B, as well as for two sets of samples in Figure 3A. The Author was able to provide data for this figure, but these did not resolve the Editors' concerns. The Author is also not able to provide the original data for the other figures. Editors therefore no longer have confidence in the results reported in this study.


H.-Y. He agrees with the retraction and its wording.
