Hi,

I want to remove stray voxels from my t-statistic sub-brik maps, for example, by defining a threshold (ex: p<0.05) and masking out voxels based on a minimum number of neighbors (ex: 1 voxel) that are activated (in 3D). Preferably, outputing a new map that has been masked.

I see I probably want to use 3dmerge, but I'm lost on the options to use. Can somebody give me a hand?

thanks
mark
