Possibly there are conflicting definitions of frames -1, -2, and -3 here
(and that's leaving out the possibility of -0, -1 and -2 counting). Some
will count from the first base (start for forward strand), others the last
base (start of reverse strand). This can make comparing the output
of different tools quite confusing.
