I have a couple PWMs for RNA binding proteins and I also have the sequences of candidate UTRs in different groups as a
DNAStringSet. I'd like to see how many of the UTRs (and which ones) in each group match a given PWM. However, it looks like the
matchPWM function in
Biostrings only supports a single sequence rather than a
DNAStringSet. Is there a way to do this besides sticking all of my sequences together, matching, breaking them apart or looping through each sequence?
