Hi experts,
I’m trying to run a paired ttest and I want to make sure I understand the wiki properly.
I have one run/trial/scan (the terms are a bit confusing so I want to be clear) and there are two conditions within the trial (humour vs erotic). I already did a lower level feat for each subject in the experiment and gathered the individual feat outputs (10 in total). I want to compare activation in the humour condition with the erotic condition for those subjects. I am now using higher-level analysis to do a paired test based on the wiki. I’ve entered the lower level feat files twice to get 20 input files and made an EV for each of the participants and an extra EV for comparing the trials.
For some reason this doesn’t feel right.
my EVs and contrasts look like the example provided in the wiki but I’m not 100% about the feat files i’m entering. I had 10 participants but I’m comparing them with themselves for a paired test so I have to enter the feat files 2x correct?
