Greedy Motif Search — Step 5 — Stepik

WebIf "AT" is the motif, this cannot overlap with another "AT" motif, therefore the request for "overlapping motifs" makes this part of the code superfluous. It would be better expressed if the motif was "ATA" for example. Thus if the sequence was ATATATA the motif is present 3 times, but only twice if the motif was contiguous. Web5.

WebGreedy Motif Search with Pseudocounts Input: Integers k and t, followed by a collection of strings Dna. Output: A collection of strings BestMotifs resulting from applying GreedyMotifSearch (Dna, k, t) with pseudocounts. If at any step you find more than one Profile-most probable k-mer in a given string, use the one occurring first. WebGreedy Motif Search algorithm are: 1) Run through each possible k-mer in our first dna string, 2) Identify the best matches for this initial k-mer within each of the following dna strings (using a profile-most probable function) thus creating a set of motifs at each step, and 3) Score each set of motifs to find and return the best scoring set.

Greedy motif search

WebExamples. GreedyMotifSearch, starts by setting best_motifs equal to the first k-mer from each string in Dna (each row assign a k-mer), then ranges over all possible k-mers in dna[0], the algorithm then builds a profile matrix Profile fro this lone k-mer, and sets Motifs[1] equal to the profile_most_probable k-mer in dna[1]. WebImplement the brute-force-median-string algorithm and the branch-and-bound median string algorithm described in chapter 4. Also implement the Greedy Motif Search algorithm. The brute force median string and greedy motif search algorithms have not been implemented yet, so you'll be doing this from scratch.
