Dear SPMers,
I want to extract data which reflects the mean level of activity in a predefined
ROI. The aim is to correlate the individual mean activity during an fMRI memory
paradigm with other subject characteristics. I have computed the individual
first level contrasts (active – rest / block design).
My question: which images should be used for extracting the average activity
in the ROIs? cons, betas or spmTmaps?
regards,
Ben
