Ontologies are the primary means to store biological data about genes, proteins, and other biological entities in an accessible and unambiguous way. These ontologies are hierarchical collections of descriptive terms, typically represented as networks (graphs), serving as a fundamental structure to store biological knowledge. The use of ontology-based enrichment and network representations to infer biological properties of gene and protein sets identified in experiments, is now ubiquitous. Consequently, a solid understanding and fluency in ontology-based approaches is an essential skill in a wide range of biological fields.
During this 4-day online course participants will learn how to access and utilize biological ontologies (mainly Gene Ontology) to arrive at sound biological inferences using standard and customized enrichment analyses and network visualization.
During the course you will learn how to:
access gene and pathway ontologies to build high-quality maps for data interpretation and visualisation;
customize query data as well as databases themselves to deal with a wide range of biases and produce reliable results using online tools, Cytoscape, and R packages;
explore Gene Ontology, KEGG and Reactome databases;
understand, utilize and create sub-ontologies to address specific biological questions by executing enrichment analyses;
Use R-based packages to automate, accelerate and create reproducible analyses;
be able to interpret and assess the quality of GeneOntology analyses in publications by understanding the strengths and limitations of enrichment calculations.
After the course you will be able to independently extract data from public resources, assess their quality, annotate your own networks and biomolecules in Cytoscape, extract data using R, and critically interpret the results.
This course is an introduction to ontologies, however we require:
working knowledge of Cytoscape (e.g. introductory level course by Matt Rogon from EMBL CBNA https://git.embl.de/rogon/introduction-to-cytoscape-and-network-biology)
basic knowledge of R (data structures, file operations etc.) - e.g. introductory level course by EMBL CSDA (https://git.embl.de/klaus/tidyverse_R_intro) or EMBL Bio-IT (https://bio-it.embl.de/events/introduction-to-r/)
Ontologies ,statistics, biases, tools, networks, interpretation, R, Cytoscape
