This directory contains the Build 33 finished human genome assembly
(hg15, Apr. 2003). The chromosomal sequences were assembled by the
International Human Genome Project sequencing centers and verified
by NCBI and UCSC.
Files included in this directory:
- chr*.fa.zip: compressed FASTA sequence of each chromosome.
Each chromosome is in a separate file in a zipped Fasta format.
Repeats -- which are shown in lower case -- are annotated by
RepeatMasker run at the sensitive setting and Tandem Repeats Finder
(repeats of period 12 or less).
The main assembly is contained in the chrN.fa files, where N is the
name of the chromosome. The chrN_random.fa files contain clones that
are not yet finished or cannot be placed with certainty at a specific
place on the chromosome. In some cases, including the human HLA region
on chromosome 6, the chrN_random.fa files also contain different
haplotypes from the main assembly.

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.cse.ucsc.edu, then
go to the directory goldenPath/hg15/chromosomes. To download multiple
files, use the "mget" command:
mget <filename1> <filename2> ...
- or -
mget -a (to download all the files in the directory)
All the files in this directory are freely available for public use.
