For microarray work I would have to say using R/Bioconductor will

probably be more sensible for the very practical reason that they

have a much larger community using microarrays than Python does.

I am working at getting up to speed with R and bioconductor. I ask the
question here as I got such a great answer for the last question I had and
thought if the tool was available in biopython then I would try it. I don't
know how this problem is normally solved.
