edgefire lines up a brain MRI scan with a reference scan. It runs entirely in your browser, so your images are not uploaded.
Choose the scan to move on the left and the reference in the middle, then click Go. The aligned result appears on the right. If the moving scan includes the skull, click Brain Extract first.
