I have been trying to start using MS-DIAL to perform a metabolomics study using the negative ion mode. I have tried setting different parameters and uploading different files, however, I always get the same message: "There is no peak information for peak alignment. Please check your ion mode setting", then another message: "There is no peak information in (sample name). So please select other files or check ion mode for it and re-analyze it with the ion mode setting". What should I do?
