Hi Afni community,
I am running 3dttest++ to run one sample ttest and i want to regress the effects of scanner in my analysis. for example, I have 5 different datasets that have been acquired over 5 different scanners and i wanted to set up my scanner covariate file like this and then use 3dttest++ command :
3dttest++ -prefix result -setA 'subject_data'
-covariates scanner_covariate.txt
-covariate_center DIFF
Subects
subj01 1 0 0 0 0
subj02 0 1 0 0 0
subj03 0 0 1 0 0
subj04 0 0 0 1 0
subj05 0 0 0 0 1
I want to male sure if i am setting the covariate file right.
Thank you for your comments and suggestions.
