Hi Hiroshi,
I am going to use the MS-DIAL to process metabolomics raw data produced by uplc-qTOFms (Bruker Impact II). Calibration solution (Sodium formate) is used for mass calibration in my experiment. Basically, the calibration solution elutes at the dead time of the RP chromatography and the metabolites follow. However, I do not know how to do mass calibration using the MS-DIAL and I can not find the instruction about it. Should I calibrate the raw data before I input it to the MS-DIAL?
Best wishes!

Hi Yong:
In principle, ABF file converter retrieves the calibrated data. Therefore, the abf format file should contain the calibrated data if you reflected the calibration to your raw data in the DataAnalysis software of Bruker.
If you use the Bruker DIA-MS method, please read the FAQ of MS-DIAL.

Question: can we process Bruker's DIA QTOF data with MS-DIAL?
Yes. Note that for DIA (data independent MS/MS acquisition) Bruker QTOF data, the calibration segment needs to be at the end.
