Hi there -

I have a set of ROI's selected and masked based on the F-statistic and p-values generated using AlphaSim. I would now like to extract the averaged time series from each cluster (e.g., using 3dmaskave).

However - I would like to restrict the number of voxels from each cluster that go into the average. Specifically - I want to average a volume of size N, where N is the size of my smallest cluster, centered around the voxel of maximal activity in each cluster. I haven't found an option in 3dmerge or 3dclust that would allow me to do this?

Help!
Thanks.

Agatha
