Dear sir/madam: 

I have a question about SDM analysis. Say I''m interested in meta-analyzing  fRMI results for contrast [a > b]. Some studies will also report the reversed contrast [b > a]. Do I enter these coordinates and then give the T-value a negative sign to include 'deactivations'? 

Best, 

Jurriaan

Dear Jurriaan,

Yes, in order to include deactivation peaks you add the t-value with inverted sign. 

Best,

Anton

Thanks for your swift reply Anton.
