We have some first level analysis 1/2 was run with fsl3.2 and is in
analyze format (.hdr/.img), the other 1/2 was run with 3.3 and is in
compressed nifti format (nii.gz)
Off the bat, I'm wondering if this is a "Bad Idea(TM)". I'm
consistently getting an $fmri(VOLUME$rawstats) value of 0, which in
turn causes gnuplot to error out when creating the tsplots.
Looks something like this:
> /Volumes/local/fsl-testing/bin/smoothest -d 13 -m mask -r stats/
> res4d > stats/smoothness
> WARNING: Extreme smoothness detected in X - possibly biased global
> estimate.

Is this indicative of a problem with the design or could it be a
result of our mixed input formats?
