Hi Doug, I tried using the registration file in the tal-rfx dir for this group and I received the following error:

ERROR: Input volume voxel dimensions do not match those in the registration file. If the input volume is in bshort/bfloat format, check that there is an accompanying bhdr file.

Can I use the bhdr file that is in the same directory as the registration file?

There should be a register.dat file in the bold dir of the average subject (or maybe in the bold/analysis/tal dir)

Hi, I am trying to run mri_volcluster on a group ROI and am having some trouble. I was hoping someone had suggestion. I created individual ROIs and wanted to average them to obtain a group ROI. I ran isxavg-re-sess for each ROI but there is no registration file for mri_volcuster to reference. Have I hit a dead end? Does anyone know another way of creating a group ROI that I can apply the mri_volcluster command to?
