Ants, Bees, Genomes & Evolution

2016 Bioinformatics & Population Genomics

Practicals prepared with Rodrigo Pracana, Julien Roux, Rob Waterhouse and Stefan Schiffels for a 1 week Bioinformatics & Population Genomics course. [Overview slides]. We use similar material for QMUL’s Bioinformatics MSc and our Ecological and Evolutionary Genomics MSc:

• Reads to genome to gene predictions:
  Short read cleaning, genome assembly, quality control, gene prediction, quality control. [Slides]
• Population sequencing to genotypes to population genetics statistics:
  • Mapping reads, calling variants, visualizing variant calls.
  • Analysing variants: PCA, measuring Differentiation & Diversity.
• Inferring population sizes and gene flow.
• Gene expression:
  • From raw sequencing data to transcript expression levels.
  • Gene-level clustering and differential expression analysis.

2016 Learning how to program in R

As biology is becoming a data science its increasingly important to be able to wrangle large datasets. We use variations of the following for QMUL's SBC361 (3rd year Research Methods) and Bio781p (MSc Statistics & Bioinformatics):

• Practical 1: R refresher and regular expressions
• Practical 2: Functions and for loops
• Practical 3: Practice to pull it all together

Ecological and Evolutionary Genomics

Evolution

1st year introduction (part of QMUL's BIO113):

Older stuff

2012 Swiss Bioinformatics Institute Summerschool

From 2012 Swiss Bioinformatics Institute summerschool in Bioinformatics and Population Genomics (with Oksana Riba-Grognuz, Kate Ridout and Eyal Privman). This is largely superceded by the newer version (see above):

• Overview and summary slides
• UNIX introduction, de novo genome assembly & de novo transcriptome assembly, and cross-validation using Cytoscape of the genome and transcriptome assemblies [Google Docs link]
• Automated gene model prediction and manual refinement [Google Docs link]
• Differential gene expression with tophat/cufflinks/cummerbund [Google Docs link]
• Some random tips and discussion topics [Google Docs link]

2006-2010 stuff from Uni Lausanne:

• Introduction to microarray analysis: Three hour practical for 3rd year Biology students. Download normalized affimterix data, blindly use Limma to find significant genes, cluster them with TMEV, conduct GO analysis of one cluster… conclude about confounding factors in experimental design.
• Introduction to BLAST: Two hour practical for 2nd year biology students. Calculate score & evalue of an alignment by hand… compare with true Blast results obtained on NCBI, see that blastp and blastn have different sensitivities. Check some new NCBI blast features.

Semester programming projects:

• Programming project: for introduction to python/biopython class. Determining Codon Adaptation Index in ants. Required datafiles: sequence fasta file and blastx report.
• Programming project: for introduction to python/biopython class. Improved protein sequences for non-model organisms.
