A CBS-based algorithm was implemented in CNV Workshop
[14]. For CBS, LRR data were used to identify a segment in the
genome that displays a change in signal intensity. Mean LRR and
distribution of BAF were then used to predict how likely each
segment of the genome is a copy number variant. CNVs were then
called using default parameters. The CNV statistics illustrating the
characteristics of HMM and CBS were summarized in (Table S2
in File S1).
