Dear Joseph, > The manual says push the VOI button, but I cannot seem to find this? it has been renamed "eigenvariate" in the meantime (in the bottom left Interactive window, under the "Multivariate" section). This will create a VOI_*.mat file that can be used as one of the inputs to DCM. Hopefully the DCM tutorial in the SPM manual will be updated soon.
