I am working on a project related to cancer. I have RNASeq data only for tumor samples and matched Tumor/normal samples for WES data. I have performed WES calling on Tumor/Normal Sample. Now I wanted to analyze RNASeq data. Since I don't have matched Normal Control data for RNASeq so I couldn't able to do DE analysis. Could someone please suggest to me what other types of analysis I can perform considering that I have the only tumor RNA-Seq data. I have the RNA seq sample of around 16 patients.
