pfm_to_igm: Convert PFM to IGM.

In mPloenzke/learnMotifs: Learn Nucleotide Motifs via Convolutions

Description

Convert position frequency matrix into an information content matrix to be consistent with the de novo filters.

Usage

pfm_to_igm(motif.raw, motif.pos = NULL, mmax, bg = c(0.25, 0.25, 0.25,
  0.25))

Arguments

motif.raw	List of annotated motifs as PFMs.
motif.pos	Vector of indices to extract motifs. If NULL all motifs will be selected.
mmax	Maximum motif length, found via find_max_length.
bg	Vector of background nucleotide probabilities (A, C, G, T)

Value

4-D array containing IGMs of the extracted motifs.
