Virtually without exception all available tools focus on conserved segments or residues. Small divergent regions however are biologically important for specific quantitative polymerase chain reaction genotyping molecular markers and preparation of specific antibodies and yet have received little attention. As a consequence they must be selected empirically by the researcher. AlignMiner has been developed to fill this gap in bioinformatic analyses. Results AlignMiner is a Web-based application for detection of conserved and divergent regions in alignments of conserved sequences focusing particularly on divergence. It accepts alignments protein or nucleic acid obtained using any of a variety of algorithms which does not appear to have a significant impact on the final results. AlignMiner uses different scoring methods for assessing conserved divergent regions Entropy being the method that provides the highest number of regions with the greatest length and Weighted being the most restrictive. Conserved divergent regions can be generated either with respect to the consensus sequence or to one master sequence. The resulting data are presented in a graphical interface developed in AJAX which provides remarkable user interaction capabilities. Users do not need to wait until execution is complete and can.even inspect their results on a different computer. Data can be downloaded onto a user disk in standard formats. n
