Hello !

I am very new to MS/MS so apologies if my question is not clear.
I am using MHCquant to identify peptides from immunopeptidomics data. For now, I just retrieve the scan ID for each identified peptide, and I visualize the associated mass spectrum on Fresstyle (part of XCalibur).

I would like to get the peak identification in my mass spectrum when I visualize them, to know which peaks were considered as significant for peptide identification and which ion/fragment corresponds to which peak (cf image, I would like to make appear the y, b labels).

Best,
polklin
