identification error January 31, 2020, 05:01:47 PM Just wanted to report a bug I found while doing positive lipidomics. As can be seen by the images attached, MS-dial is reporting the same SM with two different m/z values but the same adduct. It looks like one of them is actually 2O (Sphingomyelin) while the other should be labeled as 3O (the Oxidized sphingomyelin). The 3O annotation does show up when I look using the compound search button. But it is being reported as 2O on the main page of the GUI and in the export sheet.
