change Fragment Ion tolerance

[AnkeTraut]

Hi all,

I would like to change the Fragment Ion Tolerence to 10 ppm but I can't find a way to change from Da to ppm. For Precursor Ion Tolerance a change between ppm an Da is possible but not for the Fragment Ion Tolerance. Have you any idea how I can change this?

I want to search raw data from a Thermo QExective. What settings will you suggest? Normally I use 10 ppm for Fragment and Precursor Ion Tolerance.

Thank you very much for helping
All the best,
Anke
