I have done a second level analysis in FEAT (voxel corrected) and I use the
cluster program to get an unbiased report of the co-ordinates of local maximas
in my zstat images.
Functionally different premotor areas (in my case SMA, dorsal PMC, ventral
PMC) are reported as one cluster since the PMC cluster in the thresh_zstat
image is continous. However, there are very few voxels making it one
continous cluster and not three smaller ones, which is how we would expect it
to be. The cluster seperates into three if I change the threshold to 0.01, but I
would like to keep it at 0.05 for comparison reasons.
Is there any way that I can affect the cluster delimitation in the cluster
