Dear Rick,

Thank you for your answer.
I attached files that I want to perform in my study (captured by other articles).
For example, as comparing two conditions in the group analysis (condition A – condition B), there are two activations.
Then, I want to see correlations between signal changes of these two activations and individuals’ characteristics measured by self-report questionnaires (like figure 1).
And, I want to compare signal changes of these two activations across conditions and groups that I divide based on participants’ characteristics (like figure 2).
I am not sure whether I understood your comment exactly.
But, I would need to directly compare the beta weights in my group of subjects for my purposes.
Am I correct?
And, in that case, could I still use the “3dcalc” examples for my purposes?
