Definition of contrast for multiple post hoc t tests

Dear CONN user

I am struggling with the definition of multiple between-sources contrasts in a ROI-to-ROI analysis. I need to define these contrasts as post hoc tests after running an ANOVA.

The general setup: one group, repeated measures, 4 conditions and 45 ROIs (ROI-to-ROI analysis). The ANOVA yielded several significant results. Now, I want to restrict post hoc t tests to these significant results. However, I am failing to define a combined between-sources contrast for all these results. It seems, that the results shown in the result explorer are not restricted to the connectivity results of the ANOVA but rather still represent all possible combinations of the 45 ROIs. 

I have tried several contrast like

[-1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0;-1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0...]

[-1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0];[-1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0] ...

etc

But nothing worked. Can anybody give me a hint? That would be highly appreciated. Thank you very much!
