As the size of input datasets increases, the time-cost of current conservation methods is becoming unafTordable. We propose a new software tool that combines several estimation methods applied to the conservation computation process with parallelization and divide-and-conquer techniques substantially improving its performance without affecting its accuracy. We have also made an in-depth analysis of the impact of different methods and parameter selection on the alignment process applied to input datasets prior to their conservation analysis. We have used sets of mitochondrial DNA sequences with different levels of heterogeneity and length, to provide a full case study. Both the software tool and the input datasets used in this research are freely available at http://www.zaramit.orglconservation_index2015http://zaguan.unizar.es/record/4862310.1109/BIBM.2015.7359887http://zaguan.unizar.es/record/48623oai:zaguan.unizar.es:48623info:eu-repo/grantAgreement/ES/DGA/T27info:eu-repo/grantAgreement/ES/MEC/FPU-AP201O-1058info:eu-repo/grantAgreement/ES/MINECO/TIN2011-27479-C04-01Proceedings (IEEE International Conference on Bioinformatics and Biomedicine) (2015), 1434-1440All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
