Dear SPMers, When I specify : Realign and Unwarp Coreg: Estimate with an output of Realign and Unwarp (mean unwarped image) used as an input to Coreg and I then replicate both for another subject: Does the dependency link need to be updated so that it links the second Coreg to the second Realign rather than the first, or does it already link to the most recent Realign ? cheers Goulven
