Preface and Overview

Proteomics was one of the first omics fields I worked with, especially through protein-level interpretation and GO functional annotation.

This system is both a return to that foundation and a refreshed, reproducible guide for modern proteomics result interpretation.

Results-First Approach

Many researchers do not begin proteomics analysis from raw mass spectrometry files. They often receive processed result files that include protein abundance tables, log2 fold-changes, p-values, and adjusted p-values.

This guide begins from that practical starting point.

System Goal

The goal is to move from thousands of differentially abundant proteins to clear biological themes, candidate proteins, pathways, networks, and a reproducible report.
