Introduction to Biomedical Ontologies #4: Ontology Term Enrichment Using RatMine

submitted by: jennifer.r.smith
You've done your experiments and you have a list of genes that might be of interest, but…what now? Or you keep seeing the term "ontology term enrichment analysis" in the papers you're reading and, well, you have a vague idea of what that means, but you aren't really sure. Whether you're interested in information about gene functions, diseases, phenotypes or pathways, this video provides an overview of what ontology term enrichment analysis is and how you can use the "widgets" in RatMine...

Introduction to the RGD Phenotypes and Models Portal

submitted by: jennifer.r.smith

Despite what our name might imply, the Rat Genome Database contains much more than just genomic and genetic data for the rat. This video will give you an overview of the RGD Phenotypes and Models portal—a rich resource of information on topics including animal husbandry, identifying what rat strains are good models for certain human diseases, and normal physiological measurements for a variety of rat strains.

Introduction to Biomedical Ontologies 3: Anatomy of an Ontology Annotation, part 2

Are you missing the added value that you could be getting from ontology annotations? You know what ontologies are—maybe you've even used them on occasion. But if the only part of an ontology annotation that you take into account is the term itself, you could be skipping over valuable information that the other components of annotations supply. This video will give you insight into what that "valuable information" is and how to interpret what you see when you examine ontology annotations.

Do you find that, like many who use biomedical ontologies, the only part of an ontology "annotation" you use is the ontology term itself? Perhaps you've noticed from time to time that there are some other things that seem to tag along with the ontology term but never really paid attention to those. Or perhaps you are just learning about ontologies and you want to know where the ontology "annotations" come from and what they are based on. This video gives a general overview of how ontology...

Introduction to Biomedical Ontologies 1: What is an Ontology?

submitted by: jennifer.r.smith

While reading an article or looking at a website, have you ever seen the term “ontology” and wondered what that meant? Do you hear people talking about using ontologies and ask yourself what the hubbub is about? This video is designed to help answer those questions. Here is a beginner’s look at what an ontology is and why ontologies are an important tool in the scientist’s toolbox.

It’s easy to get lost on the biological superhighway. Thankfully, we brought a map.

Biological annotations and terms have gotten a makeover with RGD’s interactive pathway diagrams. The Rat Genome Database makes biological pathways and their components easy to navigate and analyze through this newly added diagrams feature at . This video will show you how to easily access, view, and gather information from these diagrams and all the great tools they offer. See our RGD website at for more information and tools for...
