New features of MS-DIAL: 1. Modified IBF converter program to accurately calculate the decimal of ion mobility data's m/z values for accumulated MS1 spectra. 2. The normalization functions are now fully supported in ion mobility data processing. 3. Fixed the theoretical spectra of [M+Na]+ ion form of LPC and PC. 4. Fragment rule based lipid annotations were improved for several lipid subclasses especially in [M+Na]+ form. 5. Improved and fixed the programs from the feedback in MS-DIAL software forum.
