due to the fact that spm_smooth somehow changes the input as well as the output! That seems unexpected behaviour and can lead to unexpected consequences.

yea, hooray on pointers! seriously, I agree since this is not what the average matlab user expects

jorn suspects this might cause a big (problematic, exponential) increase in memory requirements, something to keep in mind. the rest is not so worried.

code identified to change: ft_prepare_sourcemodel.m ft_volumedownsample.m changed ft_prepare_sourcemodel.m (svn 7511) No change needed to ft_volumedownsample, as the intention there is to actually change the mri.(field) that is given as input.
