Hej,
What is the current best/fastest way to count all oligos of a given size
in a sequence? Is this something one could use mx.TextTools for?
Or is it still faster to use the naive way by looping over i, extract all
seq[i:i+size] and increase the count in a dictionary ...?
What if I'd like to count all word/oligo frequencies up to size N?
