Lynn, Excerpts from SPM-help#: 12-Oct-98 SnPm by "D. Lynn Flowers"@wfubmc > You suggested that we try SnPM with our design. We have attempted to do so > but cannot find an appropriate plugin. Are we missing something? There is a plugin available which *almost* does what you need. It is Multi Group: 2 groups, 1 scan per subject available at http://www.fil.ion.ucl.ac.uk/spm/snpm/#PlugIns Currently there is no 3-group comparison plug in. The best thing (without a 3-group plugin) is to use the existing plugin to do the 3 pairwise comparisons between the 3 groups. -Tom -- Thomas Nichols -------------------- Department of Statistics http://www.stat.cmu.edu/~nicholst Carnegie Mellon University [log in to unmask] 5000 Forbes Avenue -------------------------------------- Pittsburgh, PA 15213 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
