Dear Galaxy Users: The usage of our public site is growing exponentially. As a result, we are starting to implement new functionality that will allow users to gauge the size of their datasets and histories. While most changes will be transparent, you may notice some slight change in history behavior stemming from this refactoring process. Here's what you might notice and how deal with it: - Some of the datasets you've previously deleted may be resurrected in your history. Simply re-delete them if you see this happening. - You may also find that necessary metadata files are missing when you use a dataset as a tool input. These metadata files can be regenerated using the "Auto-detect" button on the dataset's "Edit Attributes" page, accessible by clicking the dataset's pencil icon. Thank you for using Galaxy! --nate Galaxy Team http://usegalaxy.org/
