XCMS Online / Features
I am new to metabolomics and XCMS. Would anyone able to tell me why there are different features with different m/z and different fold change for the same retention time in table results? I can see that feature group number is same for all different features in the same RT. I am gong to choose the significant peak for further analysis but not sure which feature should be chosen. Are they co-variant ions?
Your answer would be really helpful and appreciated.
cheers
