Very efficient software. I reached the last step of the fMRI Graph Analysis. I am comparing nodal measures between two groups. However, I cannot interpret some results. For example, when fdr (2-tailed)=0, what does this mean? Why not a value? Then anther fdr (2-tailed)=1.0000e-0.4. Two situations happens all through the result table.
In short, the fdr column gives you the highest p-value that comes out as significant after the multiple comparisons. Therefore, if you have fdr value of zero this means that no p-value is significant after multiple comparison. However, for nonzero fdr values, there exist a region (with associated p-value) that is statistically significant after the multiple comparisons. All regions with p-values less than the fdr value will be significant.
I hope this explanations help you. If there is anything more that I can do to help, please do not hesitate to contact me.
