Hello, 

I have a study wherein one group completed an intervention, with pre and post MRI data. I contrasted the data as "Baseline > post" (1, -1). I have received differential information of how to interpret the results. 

Specifically, I am confused about whether, for example, blue would indicate an overall decrease from baseline to post, or if blue indicates that connectivity was less at baseline than at post (increase over time). Then for red, if this means there is increased connectivity after the intervention, or if connectivity was greater at baseline than post (decrease over time). 

Thanks.
