This data was uploaded on 01/15/2014 in conjunction with a manuscript entitled "The generating function approach for peptide identification in spectral networks" that was accepted to the RECOMB 2014 conference. Decompress all of the *.tar.gz files to access the raw data. The specs_ms_Rep2_CID.mgf file contains all clustered MS/MS spectra used in the RECOMB paper. *.RAW - All unfiltered spectra from the following study (high/low CID/ETD decision tree MS/MS from multiple enzymes+SCX fractions of a whole yeast cell lysate). Only CID scans from the 2nd technical replicate were extracted for results reported in the RECOMB paper.
