Correction to: Nature https://doi.org/10.1038/nature14347Published online 1 April 2015

In the Supplementary Information of this Article, some errors were made in compiling the Supplementary Data file called ‘Supplementary Variant Lists’. In the first worksheet (entitled ‘subs’) the clusters to which some single nucleotide variants (SNVs) were assigned were not reported and were replaced with ‘NA’ for ‘not available’. The correct cluster numbers have now been inserted. Three mutations occurring in tumour A32 were incorrectly assigned to cluster 3 and have now been correctly assigned to cluster 2. Duplicate entries were present for some mutations in A32. These duplicate entries have now been removed. In the fourth worksheet (entitled ‘copy_number’) incorrect copy number information was reported for sample A31-c. The previous information, implying that A31-c was primarily diploid, has now been replaced with the copy number call used within the Article, which indicates that A31-c is primarily tetraploid. The Supplementary Information to this Amendment contains the corrected Excel file ‘Supplementary Variant Lists’. These corrections do not change the authors’ interpretation of the findings. The original Article has not been corrected.
