Hi Paul, Thanks for this. We can see where the error is arising - for at least one voxel the number of neighbouring voxels available for consideration in the spatial VB step is zero even though that voxel should be considered as one of its own neighbours. We're really not sure what about your data could cause this. Would you be willing to share one of the datasets with us so we can have a look at it?

Hi Flora, we always use a Mac. Have run the analysis successfully on several different macs with different data sets (all produced in the same fashion though, and all from the same study). Ran the command again with debug on as you requested. The files in Step 1 are : finalMVN.nii.gz info.txt mean_delttiss.nii.gz paramnames.txt zstat_delttiss.nii.gz freeEnergy.nii.gz logfile mean_ftiss.nii.gz uname.txt zstat_ftiss.nii.gz and step 2: info.txt logfile uname.txt Hope this helps figure it out.
