ArrayExpress – functional genomics data

ArrayExpress Archive of Functional Genomics Data stores data from high-throughput functional genomics experiments, and provides these data for reuse to the research community.

1 March 2017 - Why do we encourage researchers to share and manage functional genomics data properly?

Data sharing and management may be the last thing on your mind when you're racing to get the latest cutting-edge results for the next publication. However, as the volume and complexity of data increases (e.g. single-cell sequencing, sensitive clinical data, multi-omics), and as the drive for "open data" picks up speed for publicly-funded research, coming up with a data sharing and management plan upfront --- preferably at the project planning phase --- will save a lot of pain and misery when it comes to publishing and eventual reuse of data. To this end, we provide a user-friendly data management/submission tool Annotare that encourages proper data management and sends data to ArrayExpress for stable archiving.

Still not convinced? We hope this hilarious YouTube data management "horror story" will change your mind. Enjoy!
