Subject: [FSL] Thresholding query
Dear FSL users
I am currently running higher level (between groups unpaired t-tests)
analyses and I have a query regarding threshold values.
FSL has the Z value threshold set to 2.3 by default. My understand is that
2.3 is the equivalent to 0.01 one-tailed and 1.96 is the equivalent to 0.05
two-tailed. Is this correct?
Can somebody provide some clarification about what 2.3 and 1.96 thresholds
mean, (if I am wrong) as I have used both these values for analyses.
Thanks you.
Liam.
