Hi,

 

try ovberlaying your beta images (with regression coefficients) of the respective regressors of interest using MRIcro(n), works great for me.

 

Good luck,

 

Bas

Hello Experts,

In SPM2.

Using the PET statistical design it's really good to see the voxel wise analysis and cluster wise analysis. But when we try to display the results using "sectional", "slice" and rendering overlays we get a color bar on the diaplay, this color bar displays the "T" value in a significance test. Increasing T (increasing significance) is not same as increasing effect size. Increasing T means increased reliability (consistency) of effect. So is there a way to display the clusters or overlay the clusters with a color map that shows the effect size and not the consistency, i.e. means the significance effect and not the T values?

Thank you.

Best,
