Unable to finish importing chromatograms because the retention time predictor linear regression failed. | paga | 2021-11-04 07:11 | |||||||||||||||||||||||
Good evening, Ive been struggling with a diaPASEF (Bruker) analysis on Skyline. The experiment's goal is to find a set of 30 heavy labeled peptides on one DIA-file. I've produced a Skyline library using PEAKS but after loading the single DIA file it keeps fails. Ive been guiding the setting parameters based on the "Analysis of diaPASEF data in Skyline" document but including precursors as it is immunopeptidomics. When specifying the use of Biognosys C-11 iRT peptides, I got the following error. -------------------- Skyline version: 21.1.0.278-fe50e66f2 (64-bit) Installation ID: 5bc1d5e0-0694-49c2-87b5-7e376a14cafe Exception type: InvalidDataException Error message: Found invalid data while decoding.

The calculator From_scratch_Automatic-iRT requires all of its standard peptides in order to determine a regression. -------------------- I will attached some of these file after the failed attempt. |
