Fig. 1From: BLAMM: BLAS-based algorithm for finding position weight matrix occurrences in DNA sequences on CPUs and GPUsPosition frequency matrix (PFM), position probability matrix (PPM), position weight matrix (PWM) and sequence logo of the MYB.Ph3 transcription factor. The PFM was obtained from the JASPAR database [2]. The PPM/PWM were computed using a pseudocount α=1 and assuming a uniform background nucleotide composition (bi=0.25). The sequence logo was generated using WebLogo [32]. a Position Frequency Matrix (PFM). b Position Probability Matrix (PPM). c Position Weight Matrix (PWM). d Sequence LogoBack to article page
