[Freesurfer] T-value in QDEC or FREESURFER

External Email - Use Caution

Dear freesurfer team.

I am running an analysis betweene two groups Normal and Patients. Here is an example of my particular design diagnosis :- Normal vs Bipolar Co-variate :- Age Nuisance factor :- Total_Intra cranial volume

I would please like to know a couple of things related to QDEC 1.I am looking for difference in volume between patients and controls and the analysis. For correcting for multiple comparisons I ran Monte carlo - Z simulation at threshold of 1.3 My understanding is the analysis overall runs a two-tailed t-test first and then when we select to run MC-z simulation it iterates for multiple comparisions (by repeating the saem say 1000 times ) and gives out 'clusterwise p-value' Is my understanding correct?

2.I would like to extract T-values for the same . Are we getting cluster wise T-value similar to cluster wise p-value ? in the terminal

3. Where would I find t-values for the analysis ???

4.Are there any methods to extract T-values in qdec or freesurfer . If so,please specify.

I am enclosing screenshots from my analysis for the same . Kindly request you to please have a look please help me out with this ??

Thanking You,

Yours sincerely , Dr.Vikas Bandalli
