Dear Martin,
as Donald suggests, you should try to have a look at all of your data,
searching for something odd in them. You can try this:
>> load SPM.mat
>> spm_check_registration(SPM.xY.P)
and scroll through your entire dataset. Plotting the globals can also
give you a hint about suspicious scans:
>> figure, plot(SPM.xGX.rg)
Best regards,
Guillaume.
