Bayesiansk sekvensjustering – Probabilistisk justering med kvantificering af usikkerhed

Bayesiansk sekvensjustering behandler justering af biologiske sekvenser (DNA, RNA eller protein) som et probabilistisk inferensproblem snarere end en deterministisk optimering. I stedet for at returnere én enkelt bedste justering, samples der fra en posteriorfordeling over alle plausible justeringer givet en substitutionsmodel og gap-straf-priorier, hvorved justeringsusikkerhed kvantificeres. Det er særligt værdifuldt, når efterfølgende analyser som fylogenetisk inferens eller funktionel annotering er følsomme over for justeringsfejl.
