Thanks so much for your quick reply Dr. Smith.
I just have a some more questions, I am sorry but I am very new to the field of fMRI and though I've been doing lots of readings I'm still not sure about the details of the analysis! I decided to follow the method of "Di Martino A, et. al, Functional connectivity of human striatum: a resting state FMRI study. Cereb Cortex 18: 2735–2747, 2008" But I wasn't sure about the details of it.
Could you give me some more details on what exactly dual-regression does? is this for the group-level comparison? or does it also perform individual statistics? ... I don't quite understand where I have do define my masks as the "group maps"? ... also, if I am using dual-regression/randomize do I still need to do the WM/CSF/motion orthogonalization? I've already performed that before picking my ROIs.
Thanks for your help,
