[Freesurfer] T or Z values in QDEC

Dear Freesurfer list members,

Within QDEC I have found a number of clusters that show significantly different cortical thickness and local gyrification between two groups. The cluster summary exhibits the p value, coordinates and other information regarding the cluster, however I wanted to report the t or z values and was unsure in finding or computing this from QDEC. The p-value must be computed from one of these scores but I could not find it to be reported in any of the output.

Searching on the mailing list and tutorials, I could not find an easy solution to this.

Thanks for your time and I look forward to hearing back.

All the best,

Philip Kelly
