A number of people misunderstood my posting about unix software
here at the U. of Virginia. Eugene/SAM is not free, it is marketed by
Lark Biotechnologies for a modest price. Here at U. Va, the use of
Eugene/SAM is free (we bought a license and do not charge for computer
time). Here at UVa, we charge for VAX/VMS time but not for Unix time.
Sorry for the misunderstanding.
