This tool converts genome coordinates and annotation files between assemblies. The input data can be entered into the text box or uploaded as a file. For files over 500Mb, use the command-line tool described in our LiftOver documentation. If a pair of assemblies cannot be selected from the pull-down menus, a sequential lift may still be possible (e.g., mm9 to mm10 to mm39). If your desired conversion is still not available, please contact us.
