3dna (www.x3dna.org) is the program of choice for this. Unfortunately
the documentation on the above new web-site is difficult to find, but
the downloaded software contains plenty of examples.
You could also load the molecule into coot, place two atom (say A1+B1
and A2+B2) each to define the helix axes and calculate the cosine of
the angle as the direct product of (A1-B1)/|A1-B1| and (A2-B2)/|A2-B2|.
That's probably quicker and as accurate.
