Lift Genome Annotations
 

This tool converts genome coordinates and genome annotation files between assemblies.  The input data can be pasted into the text box or uploaded from a file.  For more information, please see our LiftOver documentation.  If a pair of assemblies cannot be selected from the pull-down menus, a sequential lift may still be possible.  For example, to lift from mm9 to mm39, lift from Mouse mm9 to mm10 and then from mm10 to mm39.
