Figure S2. Highly co-occurring aberration pairs. Highly co-occurring aberrations (P < 0.05 after Bonferroni correction) are connected by lines. Aberrations that are involved only in expected links are not shown. See Additional file 1 for aberration name abbreviations. (a) Lymphoid disorders, (b) non-lymphoid hematological disorders, (c) solid tumors, (d) carcinomas, (e) all karyotypes. Results were obtained on a dataset that includes partially defined and selected karyotypes (83% of the Mitelman Database). Legend is as in Figure 2 for (a-d), and for (e) with the addition of light red and light green colors corresponding to partial deletions and partial duplications, respectively.

Figure S3. Tumor classes with similar common aberrations. (a) Tumor class pairs with significantly high numbers of common aberrations are connected by lines (FDR 5%). Aberrations assigned to tumor classes are: (a1) significantly correlated at FDR 5%, (a2) correlated with P-value < 0.05 (uncorrected). (b) Hierarchical clustering of classes based on class similarity in sharing common aberrations. Results were obtained with a dataset that includes partially defined and selected karyotypes (83% of the Mitelman Database). Legend is as in Figure 3.
