	As far as I know there isn't any regulation that says one has
	to read both strands. I do feel it is a good idea however for
	two reasons. 1). It confirms the reading of the first strand
	and sometimes one may miss a nucleotide which was not seen in
	one of the strands reading. This may not be important in short
	fragments of DNA but it is important for large Genes.
	2). It is always nice to have confirmation of sequencing by doing
	the other stand, best of all for publication accuracy.
