Data manipulation and institute’s internal review
ResourcesData manipulation and institute’s internal review
What is this about?
A journal received an enquiry from a reader stating that they had found some discrepancies in the spectra published in the electronic supporting information for a published paper. They suggested that the discrepancies would be consistent with the spectra being manually ‘cleaned’. If this were true, the characterisation and purity of the compounds reported in the paper would be called into question.
The editor checked the spectra in close detail and verified that the discrepancies that the reader had identified were a reasonable cause for concern. The editor also checked the author’s related papers in the journal and identified a total of four papers that were affected by similar discrepancies in the spectra. When the editor contacted the lead author to discuss the concerns, they explained that ‘cleaning’ spectra to remove impurity peaks was not a practice that was carried out by their research group, and they did not believe that it had occurred in this instance. However, the researcher who had carried out the analysis had now left the group and the original data files where no longer available.
As a comparison with the original data files could not be made, the journal approached an independent expert to obtain a second opinion on the evidence available in the published spectra. The expert confirmed that there was clear evidence that the spectra had been altered and that this could be consistent with an attempt to overestimate the yields for the reported reactions.
Following this, the journal contacted the director of the institute to request their assistance in determining whether the spectra had in fact been altered. The director consulted with the lead author and the head of their facility. They confirmed that it was not possible to locate the original data due to a limitation of their archival system. They stated that their internal review had not found any ‘intentional altering of the spectra’. They stated that on that basis, the papers should not be suspected and should be allowed to stand.
This recommendation runs contrary to the evidence that we believe can be seen in the spectra, but in the absence of the original data files it is difficult to make a conclusive judgement.
