Before slashdot posts a science story it should check to see if the submitted story is accurate. The Ti pyrosequencer by 454 has a Q20 read length of 400 bases, not 20 bases. The 99.3% read accuracy described in the story is at 15-fold coverage. This means that the raw base accuracy (sequencing a template once) is much lower than 99.3%. This is in comparison to the Applied Biosystem's SOLiD instrument, which has a raw base accuracy of excess of %99.94.
