In the Report Mutation rate and genotype variation of Ebola virus from Mali case sequences, the authors have recently become aware of changes to public GenBank records that affected the sampling dates for some Ebola virus sequences collected in Sierra Leone during the ongoing outbreak in West Africa. These sequences were part of the data set analyzed in late November/early December 2014. The authors have reanalyzed the data using the corrected collection dates for the Sierra Leone viruses. These changes do not affect the overall conclusions of the Report, but they do cause two minor changes to the results of the analysis. The overall topology of the tree shown in Fig. 1, and particularly the grouping into well-supported clades, remains unchanged, but some of the details with regard to tip placement have changed. The changes in the collection dates associated with some samples also resulted in a need to recalculate the evolutionary rate estimation shown in Fig. 2. Reanalysis of the corrected data set produced a slightly higher value of 1.3 × 10−3 substitutions per site per year compared with the previous estimate of 1.0 × 10−3 substitutions per site per year. The HTML and PDF versions of the paper have been corrected.
