| + | * It turns out that a lot of the hard hand work and iterated searching to assemble the mitochondrion was not necessary, as the SOAPdenovo-assembly2/k63_w_454_contigs/ assembly now has a 14960-long contig (not scaffold!) which is an almost-full-length mitochondrion, roughly as good as the best I've managed to assemble so far. I'll combine it with my efforts and see if I can eke out a few more bases. | ||
