10 Spaced seeds Spaced seed model is generally more sensitive than the contiguous seed model Extend spaced seed model by taking into account DNA substitutions specificity

14 Transition Constrained Seeds Seed Pattern: # : obligatory match position - : joker position (dont care : transitions constrained position Weight : 8[number of # + half carries 1 bit of information whereas # carries 2 adapted to GC-rich/poor genomes

15 Spaced seeds and Transition-Constrained Seeds Seed pattern ( why and not ?) –Not chosen randomly Need to: define an alignment model. search for the best (at least a good) seed pattern according to this model. ( Sensitivity : probability to detect any alignment given by the model ) –Chosen model can drastically change the seed shape… Example Bernoulli model Markov model

16 –Bernoulli [Keich et al 02] –Markov [Buhler et al 03] –Automata (M3/M8) and HMMs [Brejova et al 03] –Homogeneous alignments [Kucherov et al 04] ATCAGTGCAATGCTCAAGA |||||.||.||||:||||| ATCAGCGCGATGCGCAAGA |||||.||.||||:||||| P( 2 ) = 0.7, P( 1 ) = 0.15, P( 0 ) = X Transition has an emission probability for each symbol Ex : P( 2 ) = 0.8, P( 1 ) = 0.10, P( 0 ) = 0.10 Probabilistic Alignment Models: HSP Alignments found by heuristic algorithms

17 Seed Design Alignment Model : Bernoulli –P(match) = 0.7, P(transition)=0.15, P(transversion)=0.15 –alignment length = 64

18 Seed Design Alignment Model : Markov –5 th Order, obtained on N.Menengitidis, S.Cerevisiae, Drosophila, and Human sequences.

19 Experiments S.Cerevisiae/Neisseiria sequences

20 To summarize... We have presented several seed models (contiguous, classic spaced seeds, BLASTZ) We introduced transition-constrained seeds and showed how they improve the sensitivity From detected seeds to detected alignments

21 2.Hit criterion What is the criterion that witnesses a potential alignment ? Restriction : only the information about seeds is available Dot plot ctcgactcgggctcacgctcgcaccgggttacagcggtcgattgct aggcctcgggctcgcgctcgcgcgctagacaccgggttacagcgt Detected alignment Detected seeds 2. Hit criterion

22 Several methods have been proposed FASTA: –Several small seeds on proximal diagonals BLAST: (single hit) –One large seed. Gapped-BLAST: (double hit) –Two seeds on the same diagonal To define a good criterion we have first to define a class of similarities we want to detect : mutation model Dot plot ctcgactcgggctcacgctcgcaccgggttacagcggtcgattgct aggcctcgggctcgcgctcgcgcgctagacaccgggttacagcgt Dot plot ctcgactcgggctcacgctcgcaccgggttacagcggtcgattgct aggcctcgggctcgcgctcgcgcgctagacaccgggttacagcgt Dot plot ctcgactcgggctcacgctcgcaccgggttacagcggtcgattgct aggcctcgggctcgcgctcgcgcgctagacaccgggttacagcgt Dot plot ctcgactcgggctcacgctcgcaccgggttacagcggtcgattgct aggcctcgggctcgcgctcgcgcgctagacaccgggttacagcgt

31 Conclusions Two improvements: –Transition-constrained spaced seeds –Hit criterion combining statistical models and advantage of single/multi hit strategies. A tool that implements both of them

32 Extensions To be done –Multi-seed approach [Li03, Bulher04, Noe04] –Seed design on the fly (non necessary static seeds). –and others …
