PFMtoPWM( motifs, id = names(motifs), name = names(motifs), seq.count = NULL, ... )
motifs |
a list of motifs represented as matrices of frequencies (PFM) |
id |
the set of IDs for the motifs (defaults to names of the 'motifs' list) |
name |
the set of names for the motifs (defaults to names of the 'motifs' list) |
seq.count |
if frequencies in the motifs are normalized to 1, provides a vector of sequence counts (e.g. for MotifDb motifs) |
... |
