Hi, I need to take individual clusters reported by SPM and turn them into ROIs so I can do a power analysis on PET scans in the same group of 8 subjects under two conditions. How do I extract a cluster and make an ROI from it that I can then uise on the raw (but normalized by radiation dose) data or on normalized (presumably z-score) data from SPM? Thanks for any help you can give.
Cheers, Graham
