Hi,
This must be readily doable and I am just missing the obvious -- I am
trying, for a long sequence, to classify each position as coming from a
particular context. Something like running nucleotide table. The things
that I have thought about doing are:
.) Making Views representing my sliding windows, but then I don't see an
obvious thing except nucleotide frequency, but that doesn't really solve
the problem.
.) Using nucleotideFrequencyAt, however, I am not sure that this function
does what I want. Since it takes an XStringSet type object rather than a
DNAString type object.
thanks, jim
