Thanks so much for adding the ion ratio features to skyline - we are currently rebuilding all of our small molecule methods in skyline and have unfortunately hit a snag. I think you previously made mention of (in the future) adding the ability to assign calibration curve regression and weighting on a per-analyte basis. Right now, via the "Document grid --> Reports --> Replicates" report we can assign analyte concentrations, but only globally. However, we have methods where our calibrators do not have all analytes at the same concentration. Is there plans to allow for a per-analyte concentration assignment as well in the future? Or perhaps there is already a way to handle this via the document grid or pivot table? Thanks for any guidance you can suggest.
