Dear Karl:
Thanks for the new function. This does a better job but still not
equal to spm96. I'm not sure what's going on. I've attached some
images for your perusal. The focused spectra images are for the part
of the signal that's preserved while the full spectra shows the
differences for the higher frequencies as well. I think the labels
are self-explanatory. The spectra are normalized for the frequency
dimension (x) put you can see that major features seem to line up.
I'm working my way through all the procedures in spm99 and spm96. I
have to say spm96 was much easier to understand. I'm sending these
results just to show you what the new function did and the nature of
the issue, but as I said I'm still verifying the various convolution
kernels, etc. It's arduous but instructive.
cheers,
Darren
