SeqPup is a free biosequence editor that has the ability
to work with large, genome-sized sequences. This ability
is still limited in various respects, but it will open
and display a test sequence of 1.8 megabases (H.influenzae).
It comes in Mac, MSWindows and XWindows flavors; try
the C++ (older) version rather than the Java version, which
probably isn't ready for genomes yet. Find it at
If you try it on a 3MB genome, let me know if it works.
