Hi Kay,

Thanks for your interest in Canopy. Do you have normal controls for the tumor samples? If so, you can use FALCON to call allele-specific copy numbers. The point mutations are stored in your VCFs. However, you should adopt stringent QC and functional annotations on these mutations. Then the ASCNs and point mutations can be fed into Canopy to infer tumor phylogeny. CODEX is for total copy number analysis and doesn’t apply to the goal you mentioned in your email.

Hope this is helpful,
Yuchao
