Hi Jeff, this might be a case for the Volumes toolbox (you will find it on the SPM extensions page) and particularly the extract data options there (either in a CheckReg context menu, or even in batch mode).

The z-score converted image is not a SPM .con image and is not directly associated with an SPM.mat.

That's my problem. I already have my results in the form of these individual z-score images and running a typical analysis or SPM.mat file to obtain these values will not work. Just looking for a simple binary analyze image mask application to results image process that will give me the values above...any thoughts on how to do this? > > Thanks to all, > Jeff Browndyke -- Volkmar Glauche Freiburg Brain Imaging http://fbi.uniklinik-freiburg.de/ Phone +49(0)761 270-5331 Fax +49(0)761 270-5416
