Dear Sara,
the CAt12 tool Threshold & Transform T-maps allows to convert to correlation coefficients if you have a regression design. The slope can be obtained by the beta estimate for the column where your regressor is defined. Let's assume your regressor is in the 2nd column then beta_0001.nii is the beta estimate that corresponds to the slope.
Best,
Christian

>Dear All,I hope you are fine. I am doing VBM analysis using the CAT12 toolbox. I am correlating the grey matter size with clinical scores. However, I cannot get correlation coefficients. Also for linear regression analysis, how to get b-coefficients?
