Dear fsl users, I want to analyse my data (controls-patients) using fsl's VBM. All my data (whole heads) have been brain extracted with BET beforehand in another analysis part. So instead of "beting" my data again (2nd step of VBM analysis) can i just modify the already extracted brains with tbss_1_preproc (1st step of VBM analysis) and omit the second step? Thank you in advance Antonios-Konstantinos Thanellas
