Dear SPM experts,
Currently I am creating a DARTEL template of 368 subjects. For each subjects I have 6 RC files (RC1 - RC6).
When I create a template based on all RC files for all subjects (6 * 368) I get an out of memory error.
However, when I create a template based on only the first three (3 * 368) RC files (grey matter/white matter/csf) my computer manages to complete the template creation.
I am wondering whether I need to use all the RC files, or if creating a template based on RC1, RC2 and RC3 also renders a valid template. If so, could I also just run 'create template' six times, each with a different set of RC images?
