In the traditional sense in which we use 'activity' in fMRI, it does not apply to resting state. Activity usually refers to evoked activity from some stimulus or event. Resting analysis typically measures connectivity. To look at resting networks, two popular methods are dual regression and seed-based correlations. I would suggest you invest a good amount of time reading about resting state analysis so you can best understand what they measure, and how you can make use of resting data to answer an interesting question.

They are multitemporal and I have to process them with FSL tools. In particular I am searching the method to compute Statistical Parametric Maps, but - as far I know - one may compute them if there are HRF and experimental task. In the case of resting state there is no one expertimental task to do, and so, my question is the following: what kind of method could I use to establish the voxel activity in RSimages?
