Dear FSL Experts,
My assumption using Feat group results is that the t-maps for each contrast are Gaussianized into Z-maps and a first threshold of |Z|>2.3 is then applied. Is this a correct assumption?
If yes, why Z=2.3 is explained to be an arbitrary threshold in FSL course (http://www.fmrib.ox.ac.uk/fslcourse/lectures/randomise.pdf)? Does |Z|>2.3 correspond to uncorrected p<0.01 voxel level?
Thanks in advance and looking forward to hearing from you,
Best,
Mona
