Everyone wants spectral libraries for something or other! How can you build them? Why not grab Bibliospec from those good people at the MacCoss lab?
What does it do? It makes spectral libraries!
How much does it cost? Nuthin!
Do the programmers know what they are doing?
...Yes. Yes, they know what they are doing....
If you are moving from DDA to DIA (say, SpectroNaut) you don't even have to learn Skyline! Just run Bibliospec on its own. I'm gonna take a swing at it soon and I'll let you know how it works out.
You can get Bibliospec here.
