small molecule sMRM - chromatogram information unavailable | paul leonhardt | 2021-06-09 05:28 | |||||||||||||||||||||||||||||||
Hi Skyline team, i currently use skyline as open-source tool to analyse data that has been acquired on a Sciex 5500 qqq instrument. My research focuses on nucleotides and their modifications, that's why i often need to detect the same [M+H]+ mass during different retention times. Currently I only want to get a quick overview of the data, so i need the chromatogram, peak area and retention times. The problem i have is that skyline most of the time only recognizes one of my isobaric sMRM transitions. I have acquired my data as full Range MRM scan and also as scheduled MRM scan. When creating the transition list for the full range MRM data i did not have so many problems - apart from adjusting the integration manually. But now when i want to use scheduled MRM data most of the time skyline does not find the corresponding chromatogram. Is there a way to assign this manually? Attached you find a file for demonstration which includes 4 results, two of them are full range and two scheduled - you will see that some transitions are only detected within the full range files even though the peaks are present. I'd really appreciate if you take a look into it Kind regards, |
