Dear Chris,
the TFCE toolbox allows to estimate both TFCE statistic as well as T statistic. The latter is the non-parametric approach to GLM in SPM and should be close to the SPM results (the more degrees of freedom the closer).
I have offered this options to have an alternative to SnPM. However, TFCE has some advantages because you can combine both voxel and cluster statistic. Maybe I should simply remove that option for the T statistic in the TFCE toolbox to prevent further confusion...
Best,
Christian
