Since the publication of the above paper, the authors have noticed an error in [Figure 1](#f1){ref-type="fig"}. During typesetting, [Figure 1F](#f1){ref-type="fig"} was mistakenly replaced by [Figure 1G](#f1){ref-type="fig"}. Thus, the two panels were shown as identical when they should have been different.

![Results of CRACR analysis for various expression conditions. The area statistic for PBM target gene enrichment (see the Materials and methods section) is plotted (*y* axis) for each window of expression-ordered genes (*x* axis), using a window size of 200 genes. Mig1 target genes are significantly enriched (**A**) among repressed genes in glucose addition and (**B**) among derepressed genes in diauxic shift (the 21-h time point is shown). Deletion of either (**C**) Tup1 or (**D**) Cyc8 results in derepression of Mig1 targets. (**E**) Induction of Rap1 target genes in genetic interactor Sin3 deletion. (**F**) Induction of Mig1 targets in the Aep2 deletion. (**G**) Negative control: no enrichment for Cbf1 targets among differentially expressed genes in glucose addition. The dotted line in each panel indicates the *P*\<0.001 significance threshold. The background color indicates gene expression fold change as depicted in the color bar.](msb201017-f1){#f1}
