Researchers withdraw 2016 article

An academic paper involving University of Queensland authors has been retracted after the researchers found errors in the computer code used to analyse some of the data. The paper, titled "A mathematical model explains saturating axon guidance responses to molecular gradients", was published in the journal eLife on 2 February 2016. UQ Pro-Vice-Chancellor (Research) Professor Mark Blows said the UQ authors had acted appropriately as soon as they realised there were potential inconsistencies. "In reproducing some of the quantitative analysis data, UQ researchers discovered inconsistences in the computer code, and they have worked with the journal to correct the scientific record, as is appropriate when errors or concerns are discovered," he said. "Following discussions with eLife editors, they decided to voluntarily retract the paper on the grounds that some of the published findings would require substantial corrections." Research leader Professor Geoffrey Goodhill said the inconsistencies were discovered in reproducing the quantitative analysis of experimental axon trajectory data. "We are extremely sorry for these errors, and for any time other researchers may have wasted as a result. The incorrect code was specific just to this paper, and we are of course taking steps to ensure such errors won't happen again in the future," he said.
