Hi, I've searched the archive still can't figure out the problem I encountered. I know that by default only 6 local maxima (LM) are reported per cluster. In one of my contrast (thresholded at z=2.0), I identified one big cluster, and Firefox reported 6 LMs: Cluster Index Z x y z 1 3.59 4 -64 48 1 2.69 10 -52 40 1 2.63 4 -46 46 1 2.54 10 -70 44 1 2.52 0 -76 38 1 2.51 18 -74 42 I's like to get more LMs within this cluster. So I performed "cluster -i cope.feat/thresh_zstat1.nii.gz -t 2.0 -n 10 --mm" and the results were: Cluster Index Voxels MAX MAX X (mm) MAX Y (mm) MAX Z (mm) COG X (mm) COG Y (mm) COG Z (mm) 1 896 3.59 4 -64 48 5.76 -64 43.7 Why only one LM was yielded? Thanks in advance. Mark
