ProteomicsHistione HCD and CID datasets for evaluation of search engines
To identify confident spectra from histone peptides containing PTMs, we present a method in which one kind of modification is searched each time. We then combine the identifications of multiple search engines to obtain confident results. We find that two search engines, pFind and Mascot, identify mo...

ProteomicsA synthetic crosslinked peptide library for benchmarking crosslinking mass spectrometry search engines
We have created a synthetic crosslinked peptide library to benchmark crosslinking mass spectrometry search engines. The unique benefit of the library is knowing which identified crosslinks are true and which are false. The data collected from mass spectrometry measurements of the peptide library wer...

ProteomicsA systematic evaluation of semispecific peptide search parameter enables identification of previously undescribed N-terminal peptides and conserved proteolytic processing in cancer cell lines
Background: Liquid chromatography- tandem mass spectrometry (LC-MS/MS) has become the most commonly used technique in explorative proteomic research. A variety of open-source tools for peptide-spectrum matching have become available. Most analyses of explorative MS data are performed using conventio...

ProteomicsThe choice of search engine affects sequencing depth and HLA allele-specific peptide repertoires.
Standardisation of Immunopeptidomics experiments across laboratories is a pressing issue within the field, and currently a variety of different methods for sample preparation and data analysis tools are applied. Here, we compared different software packages commonly used to interrogate immunopeptido...

ProteomicsPeptideForest: Semi-supervised machine learning integrating multiple search engines for peptide identification
We introduce PeptideForest, a semi-supervised machine learning approach that integrates the assignment of peptides to mass spectra from multiple algorithms to train a random forest classifier, thereby combining the results from different search engines. PeptideForest increases the number of peptide-...

ProteomicsThe power of three in cannabis shotgun proteomics: proteases, databases and search engines.
Cannabis research has taken of since the relaxation of the legislation, yet proteomics is still lagging behind. Last year we published three proteomics methods aiming at optimizing protein extraction (Vincent et al Molecules 2019), protein digestion (Vincent et al IJMS 2019) for bottom-up and middle...

ProteomicsModification localization and quality control for open database search results
Open (mass tolerant) search of tandem mass spectra shows great potential in the comprehensive detection of post-translational modifications in shotgun proteomics. However, this search strategy has not been widely used by the community, and one bottleneck of it is the lack of appropriate algorithms f...
