Hey guys,
I am having trouble with masking on the group level. From what I can tell, on the group level, only the intersection of all the individual first level masks is analyzed. This is a problem because if just one subject has, for example, OFC dropout, the OFC is excluded from analyses for ALL subjects! Is this a common problem? Is there any way to circumvent this and tell SPM to analyze the whole brain for all subjects?
I've done some digging on this topic in the archives. I've seen this problem brought up before, but no solutions presented. Has anything changed?
Thanks!
