Correction to ‘Dodging silver bullets: good CRISPR gene-drive design is critical for eradicating exotic vertebrates’

Proc. R. Soc. B 284, 20170799. (Published Online 9 August 2017). (doi:10.1098/rspb.2017.0799)We recently found an error in our calculation of the probability of a wild-type allele moving from s to j susceptible sites (), and acquiring the gene drive (), during gene-drive homing, under the assumption that multiplexed gRNAs are expressed simultaneously. In the R code provided (function GeneDriveSimRec, appendix S1), these probabilities are calculated recursively and the multiplier was missing (from line 11), where j is the number of cut target sites along an inter-site NHEJ-mediated deletion at which NHEJ …
