Using BiblioSpec for Creating and Searching Tandem MS Peptide Libraries

BiblioSpec is a software package for creating and searching libraries of tandem MS peptide spectra. Library searching provides a quick method for making peptide‐spectrum matches by comparing a query spectrum to a collection of reference spectra of known peptide sequence. Pre‐assembled libraries for several model organisms can be used as the basis of a search or custom libraries can easily be assembled. The protocols in this unit describe installing BiblioSpec, searching libraries, and creating custom libraries. Curr. Protoc. Bioinform. 20:13.7.1‐13.7.12. © 2007 by John Wiley & Sons, Inc.
