Data manipulation and omission in 'Quantized Majorana conductance', Zhang et al, Nature 2018

On November 24th 2019 we received from one of the authors of the now retracted 'Quantized Majorana Conductance' paper in Nature a pdf file with experimental notebook-quality data. Within this pdf file, we found data that appear to contradict the central claim of the paper. We have found that the original source experimental data may have been manipulated, namely cut, as well as cut out and pasted together. Furthermore, entire datasets that contradict the central claim of the Nature paper were suppressed. Our analysis was carried out between December 2019 and March 2020. We are able to publish our analysis now, in March 2021, after the authors of the Nature paper have finalized their retraction and deposited data from their experiment in full on Zenodo.
