Using a Lipid Database

[Esther Braga]

Hi,

I've been trying to use a standard database of glycerophospholipids to compare my sample with, but I always get stuck setting the m/z tolerance, where it opens a window saying it is not set properly.

Could anyone help me?! 

I would really appreciate if somebody that does this kind of work to give me a hand.

Sincerely,

Esther Braga
