With mosaic (Siemens) EPI images, does the tpattern option with to3d actually do anything? I've tried reading these images in with different tpattern specifications (i.e., alt+z, alt-z, and seq+z) to compare the effects of each, but the datasets produced all look the same. I would've thought that for the ones specified incorrectly, my slices (or perhaps my volumes) would be ordered incorrectly. Is the tpattern specification only for descriptive purposes with no effect on the images, or are mosaic images treated differently?
