Possibly - not sure….in general I think we believe that this should not be necessary for ICA component maps. Cheers. On 21 Jan 2013, at 10:02, Andreas Bartsch wrote: > Hi Stebve, > > yeah – thanks.

I feel that this can be important, especially because I want to compare standard single acquisition versus multiple acquisitions sequences.

Also a very nice recent paper from Hennig's group out recently in NeuroImage.
