Cloud Plot - XCMS November 18, 2021, 12:16:42 PM Hey everyone- I'm a grad student working on a new project. I am new to the forum and new to studying metabolomics. I have done some LC-MS work, and used XC-MS to do some data processing. I am just very confused as to what the meaning of the cloud plot is. I can't seem to find anything online that puts it in terms that are easy to understand. Can someone explain this plot? What is fold change? What does negative vs. positive mean in the cloud plot? Thanks so much!
