PennCNV, fused-lasso minimization, and DPI detected experimentally verified CNVs in 4 schizophrenia patients:(a) A duplication on 2p25.3 of Patient 1; (b) A deletion on 2p16.3 of Patient 2; (c) A duplication on 5p15.2 of Patient 3; (d) A deletion on 9q33.1 of Patient 4. In each subplot from top to bottom, the first three panels display the CNV detected by PennCNV, fused-lasso minimization and DPI respectively, the fourth panel displays in blue yi (LogR), and the fifth panel displays in green xi (BAF).
