This directory contains the Build 31 human genome assembly.
The chromosomal sequences were assembled by the International
Human Genome Project sequencing centers and verified by NCBI
and UCSC. 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
hgarchive.cse.ucsc.edu, then go to the directory
goldenPath/14nov2002/chromosomes. To download multiple files,
use the "mget" command:
mget <filename1> <filename2> ...
- or -
mget -a (to download all the files in the directory)
