Hi,
You need to add one or more demeaned covariates as separate EVs to look at correlations.
See the wiki page on GLM examples:
http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/GLM#Two_Groups_with_continuous_covariate_interaction
or other designs on that page.
All the best,
Mark

The design matrix can been seen in the attached file .I have finished statistical analysis in TBSS by the command “randomise”.Then how should I make a correlation analysis between brain and behavior . I know nothing about correlation and don’t know how to do it .
