Hi,
As Dan said - just look either side of one of your strong
edges. The difference in values there is the critical number.
If you divide the original signal by this number and then
multiply by 2*pi (6.283185...) then you should have a
correct radians input.
If you still cannot get it to work then feel free to upload
the dataset to our upload site:
http://www.fmrib.ox.ac.uk/cgi-bin/upload.cgi
and send us the reference number.
All the best,
Mark
