In these last screen captures, it seems that you applied a threshold on the p values, which you did not in your first post. What do you get if you enter “0.99” as the p-threshold in the Stat tab?
Your file selection looks a bit awkward, why do you have so many different namings for the different files? This seems to indicate not all the files you are trying to compare where processed in the same way…
It’s very difficult to give feedback on such advanced analysis. There are so many things that be done in a wrong way.
If you think there is a bug somewhere in the computation of the t-values, you could try to package an example and send it to us. Create a new subject, copy in two different folders the files you want to test, right-click on the subject > File > Export subject, upload this file somewhere and post the link here, with detailed instructions on how to reproduce the erroneous results.
