Dear FSLers
I need to get WM and CSF covariates to add as nuisance variables in my analysis
Ive begun to use FAST to segment my struct T1 images
i get out image_seg_0.nii.gz, image_seg_1.nii.gz, image_seg_2.nii.gz
how do I know which are the WM and CSF images and how do i then threshold them so that they are 80% tissue type probability? do i then run this mask on the data and get the time series and add as another confound ev?
any help much appreciated
