Fig. 1From: Predicting protein-binding regions in RNA using nucleotide profiles and compositionsConstruction of mono-nucleotide position weight matrix (mPWM). Both binding and non-binding sequences are used to generate an mPWM, in which each element (i,j) represents the log-odds score of the i-th nucleotide (i=A, C, G and U) in the j-th position (j=1,2,…, sequence length n). F in PWM +, PWM − and mPWM denotes the frequency of a nucleotide at a positionBack to article page
