Queries and unique database alignment inferred by clustering homologs Qudaich

A sequence aligner which can efficiently process large volumes of data and is suited to de novo comparisons of next generation reads datasets. Qudaich performs local sequence alignments in two major steps - i) identifying the candidate database sequence(s) and ii) generating the optimal alignment with those candidate database sequences. Qudaich can handle both DNA and protein sequences and attempts to provide the best possible alignment for each query sequence. Qudaich can produce more useful alignments quicker than other contemporary alignment algorithms.
