Using Tissue-Derived Data (Tumor/Germline via Buffy Coat WES Data and Normal/Tumor Genotyping Array Data)?

[Danielsm8]

Hello,
I'm working on a plasma cfDNA project that has paired tumor WES data and normal/tumor genotyping array data (Infinium GSA Panel). With the paired WES data that have both normal and tumor data, I can get ichorCNA to run perfectly, however, I do not have normal tissue WES data for many samples.

1. I was wondering if germline data derived from buffy coat samples can be used with ichorCNA?
2. I was also wondering if Infinium GSA panel data derived from both normal and tumor tissue can be used with ichorCNA?

Thank You!
