Thanks Daniel!
I tried with the GUI on the compressed DICOM file but it still thinks there are 300 slices and 40 time points, regardless of what options I change. So I got NIFTI format from the scanner and used 3dcopy:
3dcopy DBIEX_4_1.nii fmri1
This works great! Correct slices and timepts. The data is oblique so it is misaligned with the anat. But for some reason, 3dwarp got killed before completion:
3dWarp -deoblique -verb -prefix fmri1_warp+orig fmri1+orig
++ 3dWarp: AFNI version=AFNI_2011_12_21_1014 (Nov 21 2014) [32-bit]

Any ideas why?
