Im having trouble interpreting my color map and understanding certain parts of the tutorial.
I did dSPM unconstrained, then flattened, permutation test on sources for two conditions (neutral vs valid trial for MEG auditory experiment).
I skipped the tutorial "Difference" because we simply want to compare significant activation and not the significant difference.
After doing the stats for Neutral vs Valid, the color bar for the t stat is -2 to 2 (blue to red respectively). From my understanding, red source activation means Neutral is more active than Valid condition, and when blue it means valid is stronger/more active. Am I correct or wrong? I did read through the difference tutorial and the workflows but I'm still not fully grasping if my interpretation is correct, nor its limitations about the "sign". I also don't want to pick a scout because it's an exploratory study.
Note, I did try to follow one part of the difference tut: I computed the difference of means (absolute value of average), put that one file in process2, and also put the one stat source map, then test>apply stats, but then I get an error "output argument "outputfiles" (and maybe others) not assigned during call to "process_extract_pthrest2>Run".
Sorry for the long question, would really appreciate some advice!
