Are there any advantages/disadvantages to running a cluster analysis on a dataset with a smaller voxel size (e.g. 1x1x1 mm^3 vs 3x3x5)?
e.g. if you scan at 3x3x5, is there any sense or lack of sense in sampling at smaller voxel size (with adwarp) before you run a cluster analysis?
I've noticed that smaller voxels makes alphasim take forever..
