bioin.motif.profile_generated_string¶

bioin.motif.profile_generated_string(text, motif_profile, k)[source]¶

Return a randomly generated k-mer from Text whose probabilities are generated from profile.

Parameters:	text (string) – string dna. motif_profile (dict) – a profile matrix k (int) – length of the k-mer
Returns:	String, a randomly chosen k-mer key with respect to the values in Probabilities.

Examples

Assemble this code into a function ProfileGeneratedString(Text, profile, k) that takes a string Text, a profile matrix profile , and an integer k as input. It should then return a randomly generated k-mer from Text whose probabilities are generated from profile, as described above.

>>> text = 'AAACCCAAACCC'
>>> motif_profile = {'A': [0.5, 0.1], 'C': [0.3, 0.2], 'G': [0.2, 0.4], 'T': [0.0, 0.3]}
>>> k = 2
>>> kmers = profile_generated_string(text, motif_profile, k)
>>> kmers
    'AC'
