MSAcquisitionSimulator: data-dependent acquisition simulator for LC-MS shotgun proteomics
نویسندگان
چکیده
UNLABELLED Data-dependent acquisition (DDA) is the most common method used to control the acquisition process of shotgun proteomics experiments. While novel DDA approaches have been proposed, their evaluation is made difficult by the need of programmatic control of a mass spectrometer. An alternative is in silico analysis, for which suitable software has been unavailable. To meet this need, we have developed MSAcquisitionSimulator-a collection of C ++ programs for simulating ground truth LC-MS data and the subsequent application of custom DDA algorithms. It provides an opportunity for researchers to test, refine and evaluate novel DDA algorithms prior to implementation on a mass spectrometer. AVAILABILITY AND IMPLEMENTATION The software is freely available from its Github repository http://www.github.com/DennisGoldfarb/MSAcquisitionSimulator/ which contains further documentation and usage instructions.

DeMix Workflow for Efficient Identification of Cofragmented Peptides in High Resolution Data-dependent Tandem Mass Spectrometry*
Based on conventional data-dependent acquisition strategy of shotgun proteomics, we present a new workflow DeMix, which significantly increases the efficiency of peptide identification for in-depth shotgun analysis of complex proteomes. Capitalizing on the high resolution and mass accuracy of Orbitrap-based tandem mass spectrometry, we developed a simple deconvolution method of "cloning" chimer...

Liquid chromatography/mass spectrometry (LC/MS) based workflows, with their analytical power and potential throughput, play an important role in the discovery and validation of protein-based biomarkers. Current LC/MS workflows for biomarker discovery range from the classical shotgun proteomics approach to protein profiling strategies. However, no single LC/MS workflow has been adopted by the sc...
متن کاملOptimization and Use of Peptide Mass Measurement Accuracy in Shotgun Proteomics*□S
Mass spectrometers that provide high mass accuracy such as FT-ICR instruments are increasingly used in proteomic studies. Although the importance of accurately determined molecular masses for the identification of biomolecules is generally accepted, its role in the analysis of shotgun proteomic data has not been thoroughly studied. To gain insight into this role, we used a hybrid linear quadrup...

متن کاملMspire-Simulator: LC-MS shotgun proteomic simulator for creating realistic gold standard data.
The most important step in any quantitative proteomic pipeline is feature detection (aka peak picking). However, generating quality hand-annotated data sets to validate the algorithms, especially for lower abundance peaks, is nearly impossible. An alternative for creating gold standard data is to simulate it with features closely mimicking real data. We present Mspire-Simulator, a free, open-so...
