This directory contains the Jul. 2016 (Xenopus_tropicalis_v9.1/xenTro9) assembly of the
X. tropicalis genome (xenTro9, DOE Joint Genome Institute),
as well as repeat annotations and GenBank sequences.

Files included in this directory:
xenTro9.2bit - contains the complete X. tropicalis/xenTro9 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/

xenTro9.chrom.sizes - Two-column tab-separated text file containing assembly
sequence names and sizes.
xenTro9.agp.gz - Description of how the assembly was generated from
fragments.
xenTro9.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.
xenTro9.fa.masked.gz - "Hard-masked" assembly sequence in one file.
Repeats are masked by capital Ns; non-repeating sequence is shown in
upper case.
xenTro9.fa.out.gz - RepeatMasker .out file. RepeatMasker was run with the
-s (sensitive) setting.
January 31 2015 (open-4-0-5) version of RepeatMasker
RepBase library: RELEASE 20140131
xenTro9.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 - X. tropicalis 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 - X. tropicalis 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.
xenTro9.gc5Base.wigVarStep.gz - ascii data wiggle variable step values used
- to construct the GC Percent track
xenTro9.gc5Base.wig.gz - wiggle database table for the GC Percent track
- this is an older standard alternative to the current
- bigWig format of the track, sometimes usefull for analysis
xenTro9.gc5Base.wib - binary data to correspond with the gc5Base.wig file
see also: http://genome.ucsc.edu/goldenPath/help/wiggle.html
and http://genomewiki.ucsc.edu/index.php/Using_hgWiggle_without_a_database
for a discussion of how to use the wig.gz and .wib files for
interaction with the GC percent data values
xenTro9.chromAlias.txt - sequence name alias file, one line
for each sequence name. First column is sequence name followed by
tab separated alias names.
------------------------------------------------------------------
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/xenTro9/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/xenTro9/bigZips/ .
For a single file, e.g. chromFa.tar.gz
rsync -avzP
rsync://hgdownload.soe.ucsc.edu/goldenPath/xenTro9/bigZips/chromFa.tar.gz .
Or with wget, all files:
wget --timestamping
'ftp://hgdownload.soe.ucsc.edu/goldenPath/xenTro9/bigZips/*'
With wget, a single file:
wget --timestamping
'ftp://hgdownload.soe.ucsc.edu/goldenPath/xenTro9/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
