The story behind this version


DNA Sequence Assembler v4 is the natural evolution of the (now famous) DNA Sequence Assembler v3 software. DNA Sequence Assembler is appreciated by scientists all over the world and from all biology fields for its flexibility, complete set of tools and its mature graphic interface.... and of course... also for its unbeatable price :)


In the past DNA Sequence Assembler performed as good as the quality of the input data. And, we have encountered so many poor sequences/chromatograms, mostly because of the poor job done by obsolete base callers (such as Phred) or simply because of the incompetence of some sequencing companies. As usual, we wanted to offer EVEN MORE accurate results, so, we had to do it: to implement our own base caller. It required massive effort but (we hope) it is a very good base caller.


We hope this new powerful feature will help you to finish your sequencing work faster and with better results.
