This directory contains the Jun. 2020 (GRCm39/mm39) assembly of the
    mouse genome (mm39, Genome Reference Consortium Mouse Build 39 (GCA_000001635.9)),
    as well as repeat annotations and GenBank sequences.

For more information about this assembly, please note the NCBI resources:

    https://www.ncbi.nlm.nih.gov/bioproject/20689

Files included in this directory:

mm39.fa.gz - "Soft-masked" assembly sequence in one file.
    Repeats from RepeatMasker and Tandem Repeats Finder (with period
    of 12 or less) are shown in lower case; non-repeating sequence is
    shown in upper case.

mm39.fa.masked.gz - "Hard-masked" assembly sequence in one file.
    Repeats are masked by capital Ns; non-repeating sequence is shown in
    upper case.

mm39.2bit - contains the complete mouse/mm39 genome sequence
    in the 2bit file format.  Repeats from RepeatMasker and Tandem Repeats
    Finder (with period of 12 or less) are shown in lower case; non-repeating
    sequence is shown in upper case.  The utility program, twoBitToFa (available
    from the kent src tree), can be used to extract .fa file(s) from
    this file.  A pre-compiled version of the command line tool can be
    found at:
        http://hgdownload.soe.ucsc.edu/admin/exe/linux.x86_64/

mm39.chrom.sizes - Two-column tab-separated text file containing assembly
    sequence names and sizes.

mm39.agp.gz - Description of how the assembly was generated from
    fragments.

mm39.chromFa.tar.gz - gzipped tar file with each chromosome sequence
    in a separate file, masked as described above for mm39.fa.gz
    To extract the files into a directory:  tar xvzf mm39.chromFa.tar.gz

mm39.fa.out.gz - RepeatMasker .out file.  RepeatMasker was run with the
    -s (sensitive) setting.
    February 01 2017 (open-4-0-8) 1.332 version of RepeatMasker
    RepBase library: Dfam_Consensus RELEASE 20181026
CC    RepBase RELEASE 20181026;                                   *

mm39.trf.bed.gz - Tandem Repeats Finder locations, filtered to keep repeats
    with period less than or equal to 12, and translated into UCSC's BED
    format.

est.fa.gz - Mouse ESTs in GenBank. This sequence data is updated once a
    week via automatic GenBank updates.

md5sum.txt - checksums of files in this directory

mrna.fa.gz - Mouse mRNA from GenBank. This sequence data is updated
    once a week via automatic GenBank updates.

refMrna.fa.gz - RefSeq mRNA from the same species as the genome.
    This sequence data is updated once a week via automatic GenBank
    updates.

upstream1000.fa.gz - Sequences 1000 bases upstream of annotated
    transcription starts of RefSeq genes with annotated 5' UTRs.
    This file is updated weekly so it might be slightly out of sync with
    the RefSeq data which is updated daily for most assemblies.

upstream2000.fa.gz - Same as upstream1000, but 2000 bases.

upstream5000.fa.gz - Same as upstream1000, but 5000 bases.

xenoMrna.fa.gz - GenBank mRNAs from species other than that of
    the genome. This sequence data is updated once a week via automatic
    GenBank updates.

mm39.chromAlias.txt - sequence name alias file, one line
    for each sequence name.  First column is sequence name followed by
    tab separated alias names.

hg38.chromAlias.bb - bigBed file for alias sequence names, one line
    for each sequence name. The first three columns are the sequence in
    BED format, followed by tab-separated alias names.
    The .bb file is used by bedToBigBed as a URL to avoid having to download
    the entire chromAlias.txt file.  From the usage message:
        -sizesIsChromAliasBb -- If set, then chrom.sizes file is assumed to be a
        chromAlias bigBed file or a URL to a such a file (see above).

------------------------------------------------------------------
If you plan 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
[username: anonymous, password: your email address], then cd to the
directory goldenPath/mm39/bigZips. 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/mm39/bigZips/ .
For a single file, e.g. chromFa.tar.gz
    rsync -avzP 
        rsync://hgdownload.soe.ucsc.edu/goldenPath/mm39/bigZips/chromFa.tar.gz .

Or with wget, all files:
    wget --timestamping 
        'ftp://hgdownload.soe.ucsc.edu/goldenPath/mm39/bigZips/*'
With wget, a single file:
    wget --timestamping 
        'ftp://hgdownload.soe.ucsc.edu/goldenPath/mm39/bigZips/chromFa.tar.gz' 
        -O chromFa.tar.gz

To unpack the *.tar.gz files:
    tar xvzf <file>.tar.gz
To uncompress the fa.gz files:
    gunzip <file>.fa.gz
