i'd like to ask a question about ictal interictal direct subtraction
without comparing with a databse of normal subject:
is it possible in SPM to obtain a map of direct subtraction of ictal VS
interictal study of the same subject?
can anyone describe the exact procedure in spm?
i must reprocess the ECD database of normal subjects with my parameters or
exist a database with the ECD tracer realigned,smoothed,normalized that i
can downaload and use with the isas procedure?
thanks to all
