In the article "The Hippocampal Film Editor: Sensitivity and Specificity to Event Boundaries in Continuous Experience," by Aya Ben-Yakov and Richard N. Henson, which appeared on pages 10057-10068 of the November 21, 2018 issue, there was an error in the code used for analysis. Ben-Yakov notes, "There was a mistake in the code that aggregates boundaries over subjects. The aggregation is done in two iterations: the first iteration results in sets of boundaries, identified by different

... , that are up to 1 TR (time unit) from one another; and the second iteration calculates the average time of each set and combines sets up to 2 TRs from one another. The code mistakenly took the first boundary of the set and not the average when determining whether to combine sets. In the Cam-CAN dataset, this resulted in a shift of one boundary (of 19) by 300 ms. In the studyforrest dataset, this resulted in 7 of 161 boundaries shifting around 1-1.5 s in time, one boundary that existed in the original calculation no longer existing, and two boundaries being split into two. "This change had very little impact on the results, except from one result that changed meaningfully: The hippocampus is no longer significantly modulated by nObservers when accounting for all perceptual factors (p = 0.1). However, because the modulation by boundary salience remains, this does not affect the conclusions of the paper.
