Hello everyone. I'm looking at the abundance of 6 lipid signalling molecules (Lysophosphatidic acid) in plasma samples of cancer. I have performed MS analysis and quantified over 80 samples. I would now like to see if there is a "fingerprint" of these molecules in cancer, i.e. whether the expression profile of these lipids can be used to predict or identify cancer samples. So, could anyone suggest a software that would allow me to perform such an anslysis (maybe something like the biomarker discovery software on the Biorad SELDI instrument). Thank you.
Hi Mariati, i am not sure if i got your point, but may be you can try machine learning like cluster analysis to sort the samples you have in groups to see if you can sort them in groups if you already quanitifed your samples in plasma of cancer patients and healty individuals you can try support vector machines to build classification model.
Hi Bassel, thank you very much for your answer. Sorry I took a long time to reply. I was actually exploring the principle cluster analysis (PCA) and I think it might give me some directions and the results that I am looking for.
Thank you again.
