BiblioSpec does not know how to read .raw files, so I think you have to convert your .raw file to something like .mzML.
When you have your .ssl file and .mzML file next to each other, then, in Skyline, I believe you can do:
File > Import > Peptide Search
and Skyline will guide you through creating a spectral library from the .ssl file, and then extracting chromatograms from the .raw file.
I am not sure what your question about MS1 filtering protocol is.
It might be helpful if you took a look at the MS1 full scan filtering tutorial:
You do not need peptide search results in order to extract chromatograms for peptides.
The steps to do MS1 extraction are:
1. Use the menu item Settings > Transition Settings to bring up the Transition Settings dialog.
On the "Filter" tab, change the "Ion Types" to "p" (for "precursor")
On the "Full Scan" tab, change the "MS1 filtering Isotope Peaks Included" to anything other than "None".
2. Use the menu item Edit > Insert > Peptides and enter the list of peptide sequences you want.
3. Use the menu item File > Import > Results to tell Skyline where to find your .raw file.
However, the advantage of creating the .ssl file is that you are telling Skyline what the retention time is of all of your peptides, and Skyline will do a much better job of choosing the correct peak if Skyline has that retention time information.
