sequence trace files format problem

Dr. Burch,

We use Michael Zody's (Whitehead) Java TraceViewer and have no problem
on the Macintosh.  There is a demo of the TraceViewer here...

and the distribution is available here...

The only caveat is ABI trace files need to be converted to SCF format.
This can be done easily with the makeSCF program in the Staden Package
(available free to Academics).
