When I finished the 5 groups meta XCMS analysis and got about 40 common feature products. However, I read the protocol, and found the common feature products did not have the name even the raw xcms data set with information. My first question is which feature I could use to track the common feature products name? the "mzmed" or "rtmed".
I have tried to filter the common feature product with the different group raw xcms data, and found the overlap rate pretty low, just about 70% percentage. So my second question is the common features is really come from the each group raw data?
anyone could help me? thanks
