Hello,

I'm trying to use copy number variation data in a model 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.

"Analyze" is quite broad. It's unclear what you want to do or what the outcome of this analysis should be.
