This directory contains the data files required as input to 
the liftOver utility. This tool -- which requires a Linux 
platform -- allows the mass conversion of coordinates from 
one assembly to another. The executable file for the utility can 
be downloaded from

The file names reflect the assembly conversion data contained within
in the format <db1>To<db2>.over.chain.gz. For example, a file named file contains the liftOver data needed to convert hg15 
(Human Build 33) coordinates to hg16 (Human Build 34). If no file is 
available for the assembly in which you're interested, please send a 
request to the genome mailing list ( and we will 
attempt to provide you with one.

To download a large file or multiple files from this directory, 
we recommend that you use ftp rather than downloading the files via our 
website. To do so, ftp to, then go to the 
appropriate goldenPath/<assembly>/liftOver directory. To download multiple 
files, use the "mget" command:

    mget <filename1> <filename2> ...
    - or -
    mget -a (to download all the files in the directory)

Please refer to the credits page 
( for guidelines and
restrictions regarding data use for these assemblies.
