Hello,
I'm trying to use copy number variation data in a statistical model "regression" so I have for example gene expression data and SNP data for breast cancer, which is one data point for each patient.
the CNV data is different for each patient there are 23 chromosomes and several segment means, I downloaded the file for tumor data
if anyone can just clarify to me how to analyze such data, Thanks.
The data is about Breast Cancer data BRCA, downloaded from FireBrowse

A good place to start is to clarify what you mean by 'analyze such data' -- what is your scientific research question, and what do you think you need to do to answer the question?
