What's your cmd line? What's the output?
I've pasted the script I used and the output below. You can see that there is no mention of projfract-avg in the output.
By the way, it seems that it is ignoring the voxel resolution in the registration file and instead using the (erroneous) resolution in the source volume. That is, all of the activation is painted onto the midbrain. I assume that it is related to this warning:
WARNING: the voxel resolution in the source volume (1,1,1) differs from that listed in the registration file (3.125,3.125,3.5)
The bfloats and hdrs were generated with fourier, so there is no .bhdr file. Anyway, it seems to me that it would be better to trust the voxel resolution in the registration file.
