Yes we're still out here in the voids of netland.  As to linkage software there
 is quite a bit floating around - I include a copy of a post some months ago
which summarizes the responses received to a post aking avout (about) linkage a
nalysis software.  I've lost the name of the poster but S. Smith at AL SALK
comes to mind - but don't quote me on that.

Best of luck,

You may want to try the LINKAGE package.  The DOS version is available from:

	Dr. Jurg Ott
	Columbia University
	Box 58 722 West 168th Street
	New York, NY 10032
	E-mail: ott at nyspi.bitnet

There is also a VAX/VMS or Unix version available from Dr. Mark Lathrop at the
Centre d'Etude Polymorphisme Humain in Paris.  Please let me know if you need
the address.

The LINKAGE package is freely-distributed and is widely used for constructing
linkage maps in humans.  There is also a version designed specifically for
experimental crosses.

An alternate package is also available, called the Programs for Pedigree
Analysis.  This package of programs is available from:

  	Dr. Kenneth Lange
  	Department of Biomathematics
  	University of California Los Angeles
  	School of Medicine
  	Los Angeles, CA 90024-1766

This package is written in FORTRAN and is very easy to port to almost any
machine with a good FORTRAN compiler.  The MENDEL portion of this package has
been used to construct linkage maps in humans (See the most recent issue of the
American Journal of Human Genetics).

There is a very good alternative if you are familiar with linkage analysis,
computers and programming.  It is the LINKAGE package by Lathrop et al.  It is
available for DOS, VMS and Unix systems.  I would recommend against using it
under DOS for anything but small problems.

To pick up a copy do an anonymous FTP to corona.med.utah.edu (
and cd pub/linkage/vms and take it from there.

Attached is a list of programs available from us for genetic linkage analysis.
The LINKAGE program set is probably suitable for the analysis of those sheep
families. These programs are what most people in human linkage analysis use
nowadays.  I currently distribute only the PC version.


These programs are designed for IBM type microcomputers, unless indicated

On disks 5a-5c, below, you will find the current PC version (5.10) of the
LINKAGE programs for general and 3-generation pedigrees.  Versions prior to 5.1
are no longer supported by us. A version for OS/2 is also available (disk 4).

The HOMOG and Linkage Utility programs are now written in standard Pascal and
compiled with with Prospero Pascal.  Execut able code is available for DOS and


1. Below, sets of files are arranged as numbered disks. Most of these 'disks'
hold up to 360 KB characters, but some (identified with 'DD') contain up to 720
KB, and some ('HD') contain up to 1.4 MB.  To order programs, send this
pamphlet, with the desired items circled (we will return a new pamphlet).
Enclose the appropriate number of formatted disks to hold the programs desired,
either IBM PC 5-1/4" 360 KB, or high-density 5- 1/4", or 3-1/2" disks (DD or
HD) that we will then return (high-density disks hold several of the items
listed below).  Notice that 360 KB disks will be written on a high-density
drive so that they may not be readable on a low-density drive.  For 3-1/2"
disks, do NOT format a disk labelled DD as a high-density disk.


2. Enclose one extra empty disk to help cover postage.
3. Enclose an address label (possibly self-sticking) with your address on it.

Regular orders---Disks are sent out approximately once a week.  No cost.

Rush orders---Disks will be mailed on the day the order is received.
Handling charges (rush orders only):

     $100 for postal mail, or Express service charged to your account.
     $120 when sent by Federal Express charged to our account.

Forms of payment:  (1) Check made out to Columbia University, enclosed with
your order; or (2) Letter stating that you will pay an invoice sent with the
disks (government purchase order ok).

Mapmaker is available for other 'not fancy' systems as well. We have it running
under UNIX with no fancy graphics capabilities.
