Dear SPM user's,

This might sound to be a very basic question but I would like to know what is the difference between 'normalization to EPI template' and 'normalization with the parameter file generated after segmentation step (as given in example data set of SPM8 manual)' ?

Which option should be used?

If I use the later option doesn't it mean that, I am actually not normalizing all the subjects to a common template?

Thanks in advance,

What do you use as a decimal point? SPM is happy with 1.23, but may
not be so happy with the usual Norwegian 1,23.

Best regards,
