Failed importing results dur to "an item with the same key has already been added" yuanys  2018-10-15
 

To whom it may concerned,
Thank you so much for your time. I change some transitions today (by insert the transition into the skyline for small molecular) and when I re-import the resluts I got the lines below. Please let me know how to solve it.
best wishes
Yuanyuan

We have not seen that error before. It would be very helpful if you could send us your Skyline document and that .wiff file.

In Skyline, you can use the menu item:
File > Share > (complete)
to create a .zip file containing your Skyline document and supporting files.

If that .zip file and your .wiff file are less than 50MB, then you can attach them to this support request. Otherwise, you can upload them here:
https://skyline.ms/files.url

My guess is that this bug has something to do with the way that Skyline matches up peptides in your document to chromatograms in your .wiff file, but I'm not really sure.
