I'm having some trouble with 3dfim+, getting all zeros in the bucket file.

> 3dfim+ -input all+orig -ideal_file profile.1D -out All -bucket buc1

> 3dinfo buc1+orig
Dataset File: buc1+orig
Identifier Code: XYZ_JUy7AZCVDQvR41mkcQ2hrg Creation Date: Wed Feb 25 20:01:45 2004
Dataset Type: Func-Bucket (-fbuc)
Byte Order: LSB_FIRST [this CPU native = LSB_FIRST]
Storage Mode: BRIK file
Data Axes Orientation:
first (x) = Left-to-Right
second (y) = Anterior-to-Posterior
third (z) = Superior-to-Inferior [-orient LAS]
R-to-L extent: -118.125 [R] -to- 118.125 [L] -step- 3.750 mm [ 64 voxels]

But the AFNI plugin works, and so does 3dfim:

> 3dfim -input all+orig -ideal profile.1D -prefix buc2

> 3dinfo buc2+orig

I'm running it on a linux_gcc32 platform, in case it matters. Any HELP?
