In my quest to create ROI-defined timedumps of voxel-wise deviations from overall signal mean from each voxel measured across the scanning run, my script features the command:

3dTstat -prefix TimeSerAvg par12dsbpf+orig

where par12dsbpf+orig is the 3d+time EPIRT dataset (which has undergone despiking followed by bandpass filtering) that I wish to "average" into a single (non +time) volume, dubbed "TimeSerAvg"

This results in a written file, yet I cannot see this averaged brain in afni. Why can't I see it? I would expect this averaged brain to look like subject's brain at most points along a cineloop of the original timeseries.


Subsequently, I wish to use 3dcalc to include this averaged brain dataset in the denominator (expressing output as deviations from mean session signal)

Why can't I see an "averaged" EPIRT brain in afni?
