BigA

BioInformatic Genomic Analysis facility

Presentation

The use of omics technologies is essential for many projects. The local big-A facility is dedicated to the analysis of this data to allow everyone to use these approaches, which have become indispensable. The missions of the platform are:
• Support CBI teams in their omics data analysis projects by providing guidance for project setup and then assistance with data analysis.
• Develop web-applications in the form of user-friendly graphical interfaces, useful to everyone, based on requests.
• Train users in existing tools, through internal CBI training and occasional user support. Supervise master’s students, interns on the platform, or in the users’ teams.
• Contribute to the development of tools and methods for projects that require more advanced expertise and automate processing through reproducible pipelines
• Integrate the facility in the Toulouse’s bioinformatics network in collaboration with regional platforms (Genotoul Biostat), to be involved in various working groups, and to ensure technology watch.
