Dear all,
I found that when using filtered_func_data obtained from doing just pre-stats (motion
correction, filtering, and etc) as the input 4D image for Stats and Post-stats, the EPI image
where the zstats was overlayed on looks a bit more blurred compared to when just running
Full analysis. the zstats looks the same.
This is rather trivial, i think, but just wondering why there is such a difference.
Also, as a new user, i am just wondering if this is a standard procedure where you would
run prestats first, and then use the filter_func_data for the subsequent steps (stats,
poststats, registration) because every time you want to run a new GLM, you don't have to
run pre-stats again. I imagine that would save some time.
thanks
