... Hi All, I've been working on my own survival analysis of PDAC, following the tutorial https://www.biostars.org/p/153013/, but after I separated the tumor and non-tumor samples, I found that there were 179 tumor samples but only 4 non-tumor samples. I don't have too much experience with bioinformati ...
