Brief description of the tables and code availability:

Supplementary Table 1: Chromosome-arm copy number calls and aneuploidy scores for 997 human cancer cell lines.
- "makeCCLEarmcalls.R" takes the CCLE2 published ABSOLUTE data as input and calls the number of arm-level CNAs for each cell line (anueploidy score). - "makeaneuploidycalls.R" takes that output and calls the 'manyarm_events' column based on the upper and lower quantiles.

Supplementary Table 2: Genetic dependencies of highly-aneuploid cancer cells. - code for Limma runs found in Limma folder. Files: limmadrive.R and limmaachilles.R for Drive and Achilles, respectively

Supplementary Table 3: Functional annotation enrichment analysis of aneuploidy- associated genetic dependencies.
Supplementary Table 4: mRNA expression differences between near-euploid and highly- aneuploid cancer cells. - code for Limma run found in expression/limmadifferentialexpression.R

Supplementary Table 5: Chemical sensitivities of highly-aneuploid cancer cells. - code for Limma runs found in limma/drugcomparisons. Files: usinglimmaCTD.R, usinglimmaGDSC.R, usinglimma_prism.R

Supplementary Table 6: Cancer cell line sensitivity to the SAC inhibitor reversine.
Supplementary Table 7: Gene expression profiles of HCT116 and HPT cells exposed to SAC inhibitors.
Supplementary Table 8: Association between aneuploidy levels and KIF18A mRNA and protein expression levels.
