SPM SliceTiming Error: Item 'Session', field 'val': Number of matching files (1) less than required2

[Zachary Greenberg]

I'm getting this error running nipype on an ubuntu vm setup. My code looks like this:

import os

from nipype.interfaces.spm import SliceTiming

st = SliceTiming();

st.inputs.in_files = 'rIM-007-0119_brain.nii';

st.inputs.num_slices = 36;

st.inputs.time_repetition = 2.0;

st.inputs.time_aquisition = 2. - (2./36.);

st.inputs.slice_order = range(1,37,2) + range(2,38,2); # interleaved ascending

st.inputs.ref_slice = 18; # ref to middle slice

st.inputs.paths = os.getcwd(); # I'm in the current dir where the file above is located

st.run();

The error makes it sound like I'm missing an input file, but as far as I know it should only need the file to be corrected, right? Nipype is adding the matlab path to my data correctly, and spm8 is in scope as well. Stumped..

Any help is greatly appreciated.

thanks,

-Zack
