Other / Re: Peak alignment with large dataset (over 2500 samples and growing)
Hi, I'm facing the same issue and my dataset is even bigger. My question is that after you extract the peaks and do very good alignment across all the dataset A containing 10,000 samples, say with xcms, then there comes another dataset B containing 10,000 more samples. How can you align dataset B to A? Should I combine A and B together, and select peak in these 20,000 samples? Thanks very much.
