Hi,

I've been running the standard Sequenza pipeline and it works pretty well.
For some of the samples (normal-tumor pairs), the genome view shows several CN alterations (too noisy) and a depth.ratio of ~ 0.5 (see attached).
Does it mean that I have contamination? any suggestions please?
  
Thank you,

Hashem
