createFrequencyMat(substrates.seq)
Arguments
- substrates.seq
A substrate sequence
Value
A frequency matrix of amino acid from substrates.seq.
Examples
data("phospho_L6_ratio_pe")
# We will create a frequency matrix of Tfg S198 phosphosite.
idx = which(grepl("TFG\\;S198\\;", rownames(phospho.L6.ratio.pe)))
substrate.seq = Sequence(phospho.L6.ratio.pe)[idx]
freq.mat = createFrequencyMat(substrate.seq)
