====== Human HCD iTRAQ Phospho Library ======
===== Peptide Library (Nov. 26, 2014) =====
The human HCD iTRAQ Phospho library was created entirely from raw data stored on the Clinical Proteomic Tumor Analysis Consortium (CPTAC) data portal [[https://cptac-data-portal.georgetown.edu/cptacPublic/]]. Contributing laboratories were the Broad Institute and Pacific Northwest National Laboratory.

===== Decoy Library (Feb. 21, 2020) =====

The decoy library (sequence reversed) was created based on the methods described in the paper: \\ 
**Zhang, Zheng, et al.** //"Reverse and random decoy methods for false discovery rate estimation in high mass accuracy peptide spectral library searches."// Journal of Proteome Research 17.2 (2018): 846-857.
