However, results look suspicious to me and I am wondering if I am doing things correctly. It will be of great help if you could comment on some issues and check the parameters I am using.<o:p></o:p></p><p class=MsoNormal>Things I am wondering about:<o:p></o:p></p><p class=MsoNormal>(1) doing cluster statistics I get 1 big cluster that is highly significant (clusterstat: 6.5829e+006, prob: 0.0020) and includes all!!
