We have recently released our new BLAST tool, which is completely reengineered, from the initial query building screen to the results panel.
We realize that the new interface is very different from the previous version, and that it may take time and repeated usage to get used to. Please take some time to read through our newly updated BLAST tutorial to learn more about the new interfaces features and capabilities.
During this time of transition, the original BLAST tool is still available at the Legacy BLAST page.
