Hi list,

in reference to One Group (One Factor), Two Covariates

https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf1G2V#Contrast2age.mtx

that has been applied on FS-FAST fcMRI data

I obtain three folder, respectively, for "main", "covariate 1", "covariate 2".

What's meaning the sig.nii.gz that it is produced by mri_glmfit in each folder?
Please correct my conclusions if they are wrong.

1 - In the "Main" folder, the sig.nii.gz contains the results of One-sample t test regressing out the effect of the two covariates.

2 - In the "Covariate 1" folder, the sig.nii.gz contains the significant cluster that are associated with the covariate 1 regressing out the effect for the covariate 2.

3 - In the "Covariate 2" folder, the sig.nii.gz contains the significant cluster that are associated with the covariate 2 regressing out the effect for the covariate 1.

Thanks

Stefano
