I have 5D input data for my higher level MEG analysis (3 spatial dimensions, 1 time dimension, 1 subject dimension). I am currently splitting across time, running randomise at each timepoint, and recombining timeseries, but it would be a lot more powerful if I could apply TFCE or cluster-based thresholding in 4D, rather than 3. >> >> If this isn't possible in randomise at present, is there any way to get cluster to process 4D input images? At the moment it seems to just process the first slice. It would be very useful if I could identify which clusters are contiguous in time... >> >> Thought I'd post to the list in case anyone else out there is interested in doing this :) >> >> Cheers, >> Laurence >> >> =========================================== >> Laurence Hunt, DPhil Student >> Centre for Functional MRI of the Brain (FMRIB), >> University of Oxford >> [log in to unmask] >> Phone: (+44)1865-(2)22738 >> =========================================== >> > > > --------------------------------------------------------------------------- > Stephen M.
