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 http://www.soe.ucsc.edu/~kent/exe/linux/liftOver.gz.

The file names reflect the assembly conversion data contained within.
For example, the hg12Tohg16.zip file contains the liftOver data 
needed to convert hg12 (Build 30) coordinates to hg16 (Build 34).
If no file is available for the assembly in which you're interested, 
please send a request to the genome mailing list (genome@soe.ucsc.edu)
and we will 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 
hgarchive.cse.ucsc.edu, then go to the directory 
goldenPath/hg12/liftOver. To download multiple files, use 
the "mget" command:

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

hg12Tohg13.zip - A mapping of the hg12 (NCBI Build 30)
   assembly to hg13 (NCBI Build 31).  In the mapping files,
   hg12 is considered the 'target' sequence and hg13 the 'query'.

hg12Tohg15.zip - A mapping of the hg12 (NCBI Build 30) 
   assembly to hg15 (NCBI Build 33). In the mapping files, 
   hg12 is considered the 'target' sequence and hg15 the 'query'.

hg12Tohg16.zip - A mapping of the hg12 (NCBI Build 30) 
   assembly to hg16 (NCBI Build 34). In the mapping files, 
   hg12 is considered the 'target' sequence and hg16 the 'query'.
