Scientists at Biogen, Inc. developed Quickomics, a feature-rich R Shiny-powered tool to enable biologists to fully explore complex omics statistical analysis results and perform advanced analysis in an easy-to-use interactive interface. It covers a broad range of secondary and tertiary ...

High throughput (HT) screens in the omics field are typically analyzed by automated pipelines that generate static visualizations and comprehensive spreadsheet data for scientists. However, exploratory and hypothesis driven data analysis are key aspects for the understanding of biological systems, ...

Data exploration is critical to the comprehension of large biological datasets obtained by high-throughput assays such as sequencing. Interactive exploration fosters the generation of novel data-driven hypotheses...

Shotgun proteomics utilizes a database search strategy to compare detected mass spectra to a library of theoretical spectra derived from reference genome information. As such, the robustness of proteomics results is contingent upon the completeness and accuracy of the gene ...

RNA sequencing is a powerful method to build reference transcriptome assemblies and eventually sample-specific protein databases for mass spectrometry-based analyses. This novel proteomics informed by transcriptomics (PIT) workflow improves sample-specific proteome characterization of dynamic- and especially non-model organism proteomes, and ...

Mass spectrometry-based methods allow for the direct, comprehensive analysis of expressed proteins and their quantification among different conditions. However, in general identification of proteins by assigning experimental mass spectra to peptide sequences of proteins relies on matching mass spectra to ...

With the recent advent of RNA-seq technology the proteomics community has begun to generate sample-specific protein databases for peptide and protein identification, an approach we call proteomics informed by transcriptomics (PIT). This approach has gained a lot of interest, particularly ...

Researchers from the Queensland Centre for Medical Genomics have developed PGTools, an open source software suite for analysis and visualization of proteogenomic data. PGTools is comprised of applications, libraries, customized databases and visualization tools for analysis of mass-spectrometry data using ...

RNA sequencing (RNA-Seq) and mass spectrometry-based shotgun proteomics are powerful high-throughput technologies for identifying and quantifying RNA transcripts and proteins respectively. With the increasing affordability of these technologies, many projects have started to apply both to the same samples to ...

Current practice in mass spectrometry (MS)-based proteomics is to identify peptides by comparison of experimental mass spectra with theoretical mass spectra derived from a reference protein database; however, this strategy necessarily fails to detect peptide and protein sequences that are ...
