be sure to back them up in a different directory first.

This directory contains a dump of the UCSC genome annotation database for the
    $assemblyDate assembly of the $organism genome
    ($db, $assemblyLabel) $consortium.

The annotations were generated by UCSC and collaborators worldwide.

For more information about this assembly, please note the NCBI resources:
    https://www.ncbi.nlm.nih.gov/genome/$ncbiGenomeId
    https://www.ncbi.nlm.nih.gov/genome/assembly/$ncbiAssemblyId
    https://www.ncbi.nlm.nih.gov/bioproject/$ncbiBioProject
    https://www.ncbi.nlm.nih.gov/biosample/$ncbiBioSample

Files included in this directory (updated nightly):

  - *.sql files:  the MySQL commands used to create the tables

  - *.txt.gz files: the database tables in a tab-delimited format
    compressed with gzip.

To see descriptions of the tables underlying Genome Browser annotation
tracks, select the table in the Table Browser:
  http://genome.ucsc.edu/cgi-bin/hgTables?db=$db
and click the "describe table schema" button.  There is also a "view
table schema" link on the configuration page for each track.

---------------------------------------------------------------
If you plan to download a large file or multiple files from this
directory, we recommend you use ftp rather than downloading the files
via our website. To do so, ftp to hgdownload.soe.ucsc.edu, then go to
the directory goldenPath/$db/database/. To download multiple
files, use the "mget" command:

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

Alternate methods to ftp access.

Using an rsync command to download the entire directory:
    rsync -avzP rsync://hgdownload.soe.ucsc.edu/goldenPath/$db/database/ .
For a single file, e.g. gc5Base.txt.gz
    rsync -avzP \
        rsync://hgdownload.soe.ucsc.edu/goldenPath/$db/database/gc5Base.txt.gz .

Or with wget, all files:
    wget --timestamping \
        'ftp://hgdownload.soe.ucsc.edu/goldenPath/$db/database/*'
With wget, a single file:
    wget --timestamping \
        'ftp://hgdownload.soe.ucsc.edu/goldenPath/$db/database/gc5Base.txt.gz' \
        -O gc5Base.txt.gz

To uncompress the *.txt.gz files:
    gunzip <table>.txt.gz
The tables can be loaded directly from the .txt.gz compressed file.
It is not necessary to uncompress them to load into a database,
as shown in the example below.

To load one of the tables directly into your local mirror database,
for example the table chromInfo:
## create table from the sql definition
\$ hgsql $db < chromInfo.sql
## load data from the txt.gz file
\$ zcat chromInfo.txt.gz | hgsql $db --local-infile=1 \
        -e 'LOAD DATA LOCAL INFILE "/dev/stdin" INTO TABLE chromInfo;'

If you plan to download a large file or multiple files from this

directory goldenPath/$db/bigZips. To download multiple files, use
the "mget" command:

    mget <filename1> <filename2> ...

Alternate methods to ftp access.

Using an rsync command to download the entire directory:
    rsync -avzP rsync://hgdownload.soe.ucsc.edu/goldenPath/$db/bigZips/ .
For a single file, e.g. chromFa.tar.gz
    rsync -avzP \
        rsync://hgdownload.soe.ucsc.edu/goldenPath/$db/bigZips/chromFa.tar.gz .

Regents of the University of California, and made available free for
non-commercial use by Independent Researchers and Nonprofit Organizations. Any
other use of UCSC Chain Files requires a commercial license, for which users
should contact genomebrowser\@ucsc.edu. As used herein, "Independent
Researcher" means an individual who is autonomous with respect to the
research activities for which he or she uses the UCSC Chain Files (note: such
use does not extend to any use of the UCSC Chain Files at the direction and/or
for the benefit of a for-profit organization); and "Nonprofit
Organization" means a university or other institution of higher education,

laws of the country in which it is organized or located, or any nonprofit
scientific or educational organization qualified under a federal, state or
local jurisdiction's nonprofit organization statute.

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://hgdownload.soe.ucsc.edu/admin/exe/

The file names reflect the assembly conversion data contained within
in the format <db1>To<Db2>.over.chain.gz. For example, a file named
hg15ToHg16.over.chain.gz 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
(genome\@soe.ucsc.edu) 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 hgdownload.soe.ucsc.edu (user: anonymous),
then cd to goldenPath/$db/liftOver.  To download multiple files,
use the "mget" command:

    mget <filename1> <filename2> ...
