While waiting for a response, i took the root mean squared of the PE's of each basis fn from the first level, registered it to standard space and created a 4D file of each run. I did a One sample t-test using randomise on this 4D image to check for mean activation in session1 alone. I found that all the voxels in the tfce corrected p image are 0.999801. I'm not sure why this is happening? Any suggestions regarding this and the previous post? Thanks
