Clinical metaproteomics workflows within Galaxy

Comment: What is a Learning Pathway?

We recommend you follow the tutorials in the order presented on this page. They have been selected to fit together and build up your knowledge step by step. If a lesson has both slides and a tutorial, we recommend you start with the slides, then proceed with the tutorial.

This learning path aims to teach you the basics of how to perform metaproteomics analysis of the clinical data within the Galaxy platform. You will learn how to use Galaxy for analysis, and will be guided through the most common first steps of any metaproteomics database generation to searching the database, verifying the proteins/peptides, and data analysis.

New to Galaxy and/or the field of metaproteomics? Follow this learning path to get familiar with the basics!

Module 1: Database generation

Get a first look at the Galaxy platform for data analysis. We start with a short introduction to familiarize you with the Galaxy interface, and then proceed with understanding how to generate a customized database for clinical metaproteomics

Lesson Slides Hands-on Recordings

Module 2: Discovery

This section helps to guide the users through MSMS dataset search against the compact database generated in the first module. The identified peptides and proteins from various softwares will be combined later to perform verification.

Module 3: Verification

Here we use the PepQuery tool to verify the presence of the peptides as well as validate that the peptides/proteins identified are indeed of microbial origin.

Module 4: Quantitation

In this module, we perform quantitative analysis of our data using MaxQuant. Quantitative analysis will help us identify differertially abundant proteins present in the sample and their abundance in various conditions.

Module 5: Data Interpretation

We perform statistical analysis of the quantified peptides using MS stats and also used Unipept to perform taxonomic classification.
