Number of CNVs in Normal and SCZ databases based on the literature, by overlap algorithm.

1“Any” overlap means the CNVs share at least one base pair. “40% either” overlap means that the length of the overlap has to be at least 40% of the size of at least one of the CNVs. 2Normals database contains 29,292 CNVs (9,538 gains; 18,983 losses; 771 both) before any kind of internal merging based on overlap is performed. 3SCZ database contains 3,581 CNVs before omitting any CNVs that overlap with the CNVs in Normals database.
