I've written a small bioTk program for drawing linkage and radiation
hybrid maps.  It can export a map as encapsulated postscript (it just
uses tcl to dump the canvas).  We've imported the maps into Word for
Windows documents with no problems.

You can get a beta version of my program from:


We've also submitted an abstract on this program to ASHG'96.

I've gotten this program to run on PC's with tcl/tk 4.1, but it
requires a little tinkering with tkmap and some modifications to bioTk
(bioTk tries to execute "ls" to get a file listing for it's filebox).
I don't know if I can distribute a single package containing all my
modifications, but I'll try to put diffs for Windows users on my

bioTk made writing this program a cinch, as a matter of fact, I had
the first prototype for this program running in a couple of minutes,
with my boss watching over my shoulder.
