^^^^^^^^^^^^^^^^^^^^
Exactly my point it is supposed to compile overlapping sequences and
assemble them as a contig and it couldn't for me, even when there was a
60bp TOTAL homology overlap. I would be interested to hear if I am
misusing the program (I doubt that since I have been a Mac user since its
inception) or is there a bug in my version of the program. Either way I
still haven't heard back from the supplier.
Cheers, Klaus
