JISCMail - SPM Archives

I am working with an EEG dataset that has 4 conditions in each subject's data file. The data has already been pre-processed with SPM, so at present I have epoched data that has been through re-referencing, filtering, epoching, and artifact rejection. What I would like to know before I average the epochs is how to save each trial-type as a different file, so that I have 4 separate files per subject. Is there a way to do it? or do would I need to re epoch the raw data separately for each trial type? In that case, how can I specify different output names for each epoched file, if I run it as a script?
