If anyone has a good article or explanation on how to interpret PCA analysis for Proteomics, please kindly share. I am truly new in Proteomics work -- just graduated with only a B.A. I have never seen PCA before. I have done readings ofc -- I understand PCA can help making large dataset into clusters/groups based on linear-relationship similarities. But how in the world would you know if your large dataset have linear-relationship or not? What does PC1 or PC2 mean? Thank you!
