This directory contains alignments of the following assemblies:

  - target/reference: X. tropicalis (xenTro3, Nov. 2009 (JGI 4.2/xenTro3), US DOE Joint Genome Institute (JGI-PGF) (GCA_000004195.1))

  - query: Human (hg19, Feb. 2009 (GRCh37/hg19), GRCh37 Genome Reference Consortium Human Reference 37 (GCA_000001405.1))

Files included in this directory:

  - md5sum.txt: md5sum checksums for the files in this directory

  - xenTro3.hg19.all.chain.gz: chained blastz alignments. The chain format is
    described in http://genome.ucsc.edu/goldenPath/help/chain.html .

  - xenTro3.hg19.net.gz: "net" file that describes rearrangements between 
    the species and the best Human match to any part of the
    X. tropicalis genome.  The net format is described in
    http://genome.ucsc.edu/goldenPath/help/net.html .

  - xenTro3.hg19.net.axt.gz: chained and netted alignments,
    i.e. the best chains in the X. tropicalis genome, with gaps in the best
    chains filled in by next-best chains where possible.  The axt format is
    described in http://genome.ucsc.edu/goldenPath/help/axt.html .

The chainSwap program was used to translate hg19-referenced chained blastz
alignments to xenTro3 into xenTro3-referenced chains aligned to hg19.  See
the download directory goldenPath/hg19/vsXenTro3/README.txt for more
information about the hg19-referenced blastz and chaining process.

Chained alignments were processed into nets by the chainNet, netSyntenic,
and netClass programs.
Best-chain alignments in axt format were extracted by the netToAxt program.
All programs run after blastz were written by Jim Kent at UCSC.

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.cse.ucsc.edu, then go to the directory
goldenPath/xenTro3/vsHg19/. To download multiple files, use the "mget"
command:

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

All files in this directory are freely available for public use.
