I made a .ssl file, and when I tried to build a blib with it I get an error stating that the 'file' column is missing. I used Settings/PeptideSettings/LibraryTab/BuildButton, then typed blahblah as the Name, clicked next, clicked the Add Files button, and selected the attached .ssl file. A red exclamation mark appears, and if I hover over it I get the error message that I'm missing a required column called 'file'. To my eye, it looks like I have a column called 'file', but maybe my eyesight is poor.

I don't think it matters yet, but I had the thermo.raw file in the same folder as this .ssl file.
