Hi Jeff There's a script called log_roi_batch in the extension section of the spm homepage which can do what you want (http://www.fil.ion.ucl.ac.uk/spm/ext/).

The z-score converted image is not a SPM .con image and is not directly associated with an SPM.mat. I would like to obtain the following and would be willing to adopt any method to get these: > > 1.) number of voxel in the ROI > 2.) number of suprathreshold (z-score) voxels within ROI mask > > I thought about Marsbar, but it's my understanding that this would require my running a typical SPM analysis. 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 > > -- There may be fairies at the bottom of the garden. There is no evidence for it, but you can't prove that there aren't any, so shouldn't we be agnostic with respect to fairies? (R. Dawkins)
