Can you send me a .sky.zip file instead of the .sky file that you attached?
In Skyline you can use the menu item:
File > Share
to create a .sky.zip file containing your Skyline document that you did attach as well other supporting files including extracted chromatograms.
That "File > Share" menu item is the best way to create a file that you can send to other people because Skyline makes sure that it contains all of the necessary files.
Files which are less than 50MB can be attached to these support requests. You can always upload larger files here:
