Hello,

I have a batch of raw data that I am trying to import into Skyline. Some files import fine, whereas others show the chromatograms importing but then fail at the end, giving the following message:

At 17:44:

This is timstof PRM data (.d). I have tried converting to another file format but get the same error. The data will open in Bruker DataAnalysis.
Skyline version is 24.1.0.199

If anyone has any insight I would be very grateful!

Many thanks,
SF
