Correction to Supporting Information for Mehlhoff et al., Collateral fitness effects of mutations

EVOLUTION Correction to Supporting Information for “Collateral fitness effects of mutations,” by Jacob D. Mehlhoff, Frank W. Stearns, Dahlia Rohm, Buheng Wang, Erh-Yeh Tsou, Nisita Dutta, Meng-Hsuan Hsiao, Courtney E. Gonzalez, Alan F. Rubin, and Marc Ostermeier, which was first published May 8, 2020; 10.1073/pnas.1918680117 (Proc. Natl. Acad. Sci. U.S.A. 117, 11597–11607).

The authors note that, in the SI Appendix, page 6, Eq. 27 incorrectly appeared as

$$\widehat{p}=\frac{c_{io}+c_{\mathit{wto}}}{c_{if}+c_{\mathit{wtf}}}$$

and should instead appear as

$$\widehat{p}=\frac{c_{io}+c_{if}}{c_{\mathit{wto}}+c_{\mathit{wtf}}}$$

The authors note that the correct equation was used in all calculations. The SI Appendix has been corrected online.
