I am trying to combine two preprocessed VBM data sets for the final
statistical analysis with "randomise". I have processed them before
separately with the same version of FSL. They are all college students
considered normal adults and I have no reason to believe they are
significantly different samples. Do I need to re-process these two data sets
with a common template or can I just merge the pre-processed data sets and
run "randomise" with the merged data? They are all pretty large sample with
about 40 subjects each. Thank you.
