Tumor purity in TCGA data analysis

Can I ignore tumor purity issue in TCGA data analysis?

Thanks

tcga tumor-purity

Is this all the detail you can give us about your analysis? You don't even mention the kind of analysis or the underlying purpose; how do you expect anyone to help you?

Hi Ram, Thanks for your comment. I am learning the scripts from online.I don't know if the following script is essential in the TCGA data preprocessing. Thanks again.

purityDATA <- TCGAtumor_purity(colnames(dataPrep1), 0, 0, 0, 0, 0.6)
Purity.COAD<-purityDATA$pure_barcodes
length(Purity.COAD)
normal.COAD<-purityDATA$filtered
length(normal.COAD)
puried_data <- dataPrep2[,c(Purity.COAD,normal.COAD)]

from online

Please show us where exactly - give us the link to this tutorial.
