Doubts about transition list

Doubts about transition list gabidap  2024-03-27 06:46

Hello, I trying insert a transition list with M+H-H2O as adduct, but i receive the error message " calls for removing more O atoms than are found in the molecule" . What can be wrong in my list?
Many thanks

Could we have a look at the actual transition list?

Thanks for using the Skyline support board,

Shure! This is the lines with error

The problem is that Skyline wants to subtract H2O from the chemical formula for your molecule, but there isn't a formula - the molecule is described only as its mass.

That's a bug - in this case Skyline should just subtract the mass of H20 for the m/z calculation. I will make sure this is corrected in the next Skyline Daily.

Thanks for letting us know!
