Flersekvenssammenstillinger

Flersekvenssammenstillinger

Flersekvenssammenstillinger. Poengberegning for flersekvenssammenstillinger. Burde kanskje brukt en form for log odds poeng: Log Men ofte brukes sum av par (SP-poeng). SP-poeng (I, -, I, L)= p(I, -) + p(I, I) + p(I, V) + p(-, I) + p(-, V) + p(I, V). Multiple Sequence Alignments.
