I am trying to process the CNV files downloaded from TCGA database. Actually, I am not familiar with this type of data and it is the first time I am working on CNV data.
Before, with help of guys, I could extract the name of genes for each region. I was surprised when I found out many genes for each segment ( I am not biologist!!).
Currently, I want to make a matrix like [genes x segment_mean], but I don't know what should I do with these data. I searched about it in `google` as well as `Biostar` but I could not find any useful information. I appreciate if anyone help and introduce some texts, as well.
