I'm trying to draw an ROI by selecting the center of activation for a particular contrast and then selecting nearby voxels within a certain range (for example. say 20 voxels). Ideally I'd like to select only the voxels within this range that are activated by my contrast. However, I can't see how to do this, any help would be appreciated.

Thanks,

Katie
