Hi Bob,
I have just uploaded the data. It is under my name.
There are two nifti files: 1) smooth.nii and 2) nosmooth.nii.
I started analyzing the data in SPM and so the smoothing was done there (I eventually decided to use AFNI for the actual analyses for a number of reasons). I applied a 12mm filter FWHM. Outside of being coregistered to the T1 and then warped to template space, no other processing has been done on these datasets.
Just FYI, I have 3 injections/conditions for each subject in case that makes any difference in estimating the smoothness.
Thanks so much for your help.
