Skyline is a tool for quantifying mass spectrometry data by integrating chromatogram peak areas. Skyline is not a very good tool for looking at individual spectra. If you want to look at spectra in a raw file, we recommend using our tool called "SeeMS.exe", which gets installed when you install ProteoWizard.
What type of mass spectrometer did you use? Do you know what sort of data you collected?
A typical first experiment with a mass spectrometer would be Data Dependent Acquisition (DDA) where the mass spectrometer was told to collect MS1 scans and then select the largest peaks in those MS1 scans for fragmentation and identification with MS2.
If you want to get started with DDA data, I would recommend taking a look at the DDA Search tutorial:
If that tutorial does not seem helpful, you should tell us more about what type of mass spectrometer you have and what sort of data you collected. If you want to send us one of your raw files, you can upload it here:
