Hi,
I'm not exactly sure what output image you are referring to, but the main output of stage3 of the dual regression are the p-values (in the *corrp* file), but there are also output images showing you the tstat values from this (which will relate to your design matrix and contrasts, so may show "activation/deactivation" - which is a tricky concept for resting state anyway - or differences between groups, depending on how you've set it up). Also there are the results from stage2 that show the individual subject maps. Just be aware that for resting-state you should be thinking more about voxels being positively or negatively correlated with the IC timecourse, rather than "activation" or "deactivation".
All the best,
Mark
