Dear FSL team,
In the post-stats, there are two threshold can be chosen in FEAT, one is min Z (>2.3) and the other is cluster significance: P(<0.05). It is very clear for the P-value, but I have no idea about the Z-value. What does it mean?
If I wanna use Randomise common to carry out the same post-stat as the cluster Thresholding of FEAT, which options should I choose?
For example, I have two group of people, A and B, with their resting state fmri data. A seed was defined and the correlation between it and whole brain voxels had been computed for each subject. After applying Fisher'z transform to the correlation, each subject got a Z-maps. Then, I carried out a two-sample t-test between these two groups and got a raw test statistic image. What should I do to correct the P-value using the same method of FEAT by randomise command?
