Dear Jimmy and Natalie, Thanks to both of you for your quick answer. Indeed, Jimmy is right (and this was very stupid of me not to have thought about it by myself!): yes, of course, the isotopic correction in the condition.xml file accounts for the difference in the reported Libra intensities in Prophet. Indeed, i you put all of those to "0", you get back the "raw" values from the mzXML/dta file. So thanks again. I promise I will check/think more carefully next time before writing. Have a nice weekend :) Ludovic
