+ | ====== Consensus Human HCD Libraries ====== | ||
+ | ===== Peptide Libraries (May 19, 2020) ===== | ||
+ | |||
+ | The consensus human HCD libraries were created using more than 10,000 raw files | ||
+ | * available on ProteomeXchange - http:// | ||
+ | * generated at the Mass Spectrometry Data Center of the National Institute of Standards and Technology (NIST). | ||
+ | |||
+ | The libraries in the msp and NIST binary formats were updated on May 19, 2020. The new libraries of consensus spectra contain 86% more peptides than the previous version with 4-15% increase in the number of positive IDs returned for typical samples at FDR=0.01. Previous versions are available on request. | ||
+ | |||
+ | Methods used for building the libraries are presented at the ASMS 2020 conference: \\ | ||
+ | **Filtering and optimization of peptide tandem mass spectral libraries.** \\ | ||
+ | Authors: Sergey L. Sheetlin, Guanghui Wang, Dmitrii V. Tchekhovskoi , Zheng Zhang, Stephen E. Stein \\ | ||
