Design specifications

Are the data Z- or T-values?*

What is the screening threshold, also known as the clusterforming threshold or the excursion threshold (either p-value or z-value units)?*

How many subjects does the group map represent?*

Is this a one-sample or a two-sample test?*

At which alpha-level are the statistical tests carried out?

Do you want to manually specify the smoothness or estimate from the data?
Note though that estimating smoothness on statistical maps leads to biases. It is preferable to manually specify the data.*

Estimate

What is the smoothness of the data in mm?

What is the voxel size in mm?
