WHITEHEAD INSTITUTE/MIT CENTER FOR GENOME RESEARCH
HUMAN GENOMIC MAPPING PROJECT
DATA RELEASE 9 (DECEMBER 1995)
The ninth release of data from the Human Physical Mapping
Project at the Whitehead Institute/MIT Genome Center, covering data
generated through the end of December, 1995, is now available.
This data release contains YAC screening data for 15,086 sequence tagged
sites (STSs) screened on the CEPH mega-YAC library. For each STS, we
report addresses for the YACs found to contain the STS. From the data
obtained so far, there are 335 contigs assembled using single
linkage between STSs.
In addition, we also report a radiation hybrid map of the genome
containing 6193 STS markers mapped on the Genebridge Panel, as well
as integrations of the genetic, radiation hybrid and YAC contig
The data is available electronically in two ways.
ANONYMOUS FTP: The entire data release is available as a set of
Microsoft Excel files and tab-delimited ascii files on our ftp
server. Using an ftp client (such as "Fetch" on the Macintosh),
Use "anonymous" as your user name, and give your e-mail address as your

The contents are as follows:
12-95.INTRO.txt Introduction to the data release, in straight text format
12-95.INTRO.html The same in HTML (World Wide Web) format
12-95.STS2YAC.txt STS & YAC screening data as tab-delimited text.
chromosomes/ The same, split into smaller chromosome-specific files
12-95.YAC2STS.txt Inverse map of YAC to STS screening data
12-95.CONTIG2STS.txt YAC contig lists.
12-95.CONTIG2STS.txt The same, inverted.
12-95.sequence.txt Full sequences of STSs developed in-house.
pictures/ Pictures of integrated maps in Macintosh and PS forms.
rhmap/ Radiation hybrid maps.
The data is also available in compressed form using the gzip program.
THE WORLD-WIDE WEB: You will need a World Wide Web client such as
Mosaic (Unix, MS-Windows and Macintosh) or MacWeb (Macintosh).
Instruct your client to connect to
>From there, follow the "Human Physical Mapping Project" link. You will be
able to browse and download the raw data set, view the individual and
integrated maps, and to get information on the radiation hybrid and
All mapped STSs are available through the Genome Database (GDB) and

suggestions about how to make these data release most useful.
DATA RELEASE POLICY AND CITATION. Data releases are scheduled
monthly. At the end of each month, all genomic mapping data are
reviewed and prepared for distribution via CGR's electronic databases.
Data releases typically occur within a week of the close of the month.
Releases are announced by electronic messages posted to the following
two newsgroups: "bionet.genome.chromosomes" and "bionet.announce".
CGR's data release policy aims to ensure that scientific colleagues
have immediate access to information that may assist them in the
search for genes. Data releases do not constitute scientific
publication of CGR's work, but rather provide scientists with a
regular look into our lab notebooks. For projects aimed at the
analysis of particular genes or subchromosomal regions, permission is
hereby granted to use our data without the need for a formal
collaboration, subject only to appropriate acknowledgment. For
projects aimed at large-scale mapping of entire chromosomes or entire
genomes, use of the data and markers should be on a collaborative
