I have been getting the following error message when running either XPRESS or ASAP Ratio.
Found more than one variable mod on K. Please make sure to specify the heavy mass for this residue. My data is mTRAQ labeled. Lysine an n-termini are tagged with the mTRAQ reagent. I changed the labled residues appropriately for both algorithms, specified the mass difference in XPRESS (8 Da) and specified the both the light and heavy residues masses in ASAP ratio. I assume this warning indicates spectra in which both light and heavy modifications are observed? Should these results be discarded as unreliable? Am I using the input arguments incorrectly? -- You received this message because you are subscribed to the Google Groups "spctools-discuss" group.
