Week 3 — Extended Module

Week 3 — Extended Module

A hands-on, step-by-step journey from the fundamentals to applied analysis. Trainees learn how to retrieve and clean real sequence data, run core DNA/protein analyses, build high-quality alignments, and generate publication-ready outputs. Each week delivers ~15 training hours (internationally accredited, AInTP) with practical exercises and instructor feedback.

 

Week 3 — Extended Module

    Day 3:  Structures and Phylogenetics

    • Introduction to Structural Bioinformatics (5 hours)
      • Lecture (2 hours):
        • From primary to 3D structure.
        • Retrieving and viewing structures from the Protein Data Bank (PDB).
        • Predicting secondary structure (PSIPRED).
      • Practical and Tasks (3 hours):
        • Using the PDB to find and visualize a protein structure.
        • Predicting the secondary structure of a protein and interpreting the results.
        • Group task: Create a high-quality, well-annotated multiple sequence alignment for a given protein family.

Target audience
