Hi Rick,
I guess my question really boils down to: what is happening to the data in a slice itself when it is "shifted?".
Does this mean that when a slice is time shifted, the data in each voxel are re-written with an interpolated value that incorporates the values obtained for that voxel in the previous and subsequent aquisitions in some sort of trend analysis?
Alternatively, do the data values in the slice remain as they were in each voxel, only the "shifting" occurs when timing of events/blocks is convolved with the voxels in that slice-- i.e. events in time are appropriately shifted relative to when that slice was actually measured.
Please illuminate, thanks!
Jim
