Hi Giuseppe,

It seems that 3dDeconvolve is not currently able to use the
-iresp option on 1D files, which affects all of your points/
questions. I suspect that since the output is already on the
screen, it was never worth the effort to implement.

The fatal error comes from attempting to create those files
with code that doesn't support it. So for now, you will just
have to forgo the -iresp options.

The only thing you do not have is the upsampled CPSPLIN curve
(which may be a little misleading anyway, like applying a
cubic interpolation to the overlay and threshold data in an
afni display).
