The 13 Nov. 2003 chimpanzee (Pan troglodytes) Arachne assembly — NCBI Build 1 Version 1 — was produced by the Chimpanzee Sequencing and Analysis Consortium.
A genome position can be specified by the HUGO Gene Nomenclature Committee gene name of a human RefSeq, the accession number of an EST or mRNA, a chromosomal coordinate range, a scaffold (supercontig) coordinate range, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the chimpanzee genome. See the User's Guide for more information.

| huntington | Lists mRNAs associated with Huntington's disease | |
| Paabo,S. | Lists mRNAs deposited by co-author S. Paabo | |
| Use this last format for author queries. Although GenBank requires the search format Paabo S, internally it uses the format Paabo,S.. | ||
This assembly covers about 95 percent of the genome and is based on 4X sequence coverage. It is composed of 361,782 contigs with an N50 length of 15.7 kb, and 37,849 supercontigs having an N50 length of 8.6 Mb (not including gaps). The total contig length is 2.73 Gb, spanning 3.02 Gb.
Background information on the chimp genome sequencing project and the initial news release about the chimp assembly can be found on the NHGRI website. For more information about the assembly process used for this draft genome, see the Genome Browser Assembly track details page. To view a chromosome correspondence table between chimp and human chromosomes, click here. Note: this assembly does not support the new chromosomal numbering convention in which the identifiers "2a" and "2b" have been assigned to the two chimp chromosomes that align to human chromomsome 2. Instead, it retains the older numbering scheme that assigns the identifiers 12 and 13 to these chimp chromosomes. The new convention has been implemented in the subsequent chimp assembly panTro2 (Jan. 2006). See the panTro2 Gateway page for more information.
Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or the Downloads page. The complete set of sequence reads is available at the NCBI trace archive. The chimpanzee browser annotation tracks were generated by UCSC and collaborators worldwide. See the Credits page for a detailed list of the organizations and individuals who contributed to the success of this release and conditions for use of the data.
Blat searches on chrUn_random are not supported at the current time, but will be available soon.
