> How to covert the output of 3dICA.R into Z-statistic maps? Or they are already Z-maps.

There are two results in the output: a number (specified by the user) of components in time course and the mixing coefficients at each voxel (in 3D AFNI file format) associated with those component. So what Z-statistic are you referring to?
