LABORATORY BIOINFORMATICS WORKSHOP 2010

This workshop focuses on bioinformatics techniques for practical use in the laboratory. Hands-on exercises for retrieving data, primer design, BLAST searching, and genomics data navigation are covered. Primarily aimed at researchers who are new to the area, or familiar but require a quick updating, where content covered can be tailored to laboratory needs.

2009 Workshop Participants describe the workshop:

A fairly intensive course that managed to achieve a good mix between overview information and in depth details. Therefore, it highly recommendable for scientists who are new to the field of bioinformatics and provides and ideal starting point to gain further practical knowledge using bioinformatic tools. It also provided information specific to participants individual requirements.

Incredible way of fast learning about the most popular bioinformatics tools available, as well as practical examples that open a big world of ideas of how to make research. I feel much more confident now that I can quickly hone in on pertinent information and understand what I retrieve. This workshop was extremely valuable in calling my attention to many of the resources available in the public domain and how to use features I was not previously aware of. It is worth the time for this workshop!

All of the course materials for this workshop are available online.
