I am trying to discern whether there is difference in the amount of
activation between two drug conditions. The conditions are two different
drugs to the same autism patient population so that the I need to figure out
if there is any difference between autism patient population drug 1 and
autism patient population drug 2. How would I go about doing that? Thus far,
I have been using "small volume" button centered around the ROI for each
drug condition.
The problem I've encountered is, when I click that button with the
appropriate ROI, say (-42, -62, -16) for left fusiform, and say sphere, I
don't know what each one of the statistics are telling me. There is a set
level, cluster level and peak level statistics. What do those mean? I assume
that k sub E in cluster level is actually the number of voxels. This number
varies depending on whether I select FWE or not in the results section. What
is more appropriate for my study? Is it sufficient to use k sub E in the
cluster-level at the individual statistic to compare between different drug
conditions? The manuals are not helping me at this. I would greatly
appreciate an explanation on this. Thanks.
