Hi Rajeev,
there is nothing special with the contrast manager batch compared to the
other SPM5 batches. Run TASKS->BATCH->Stats->Contrast Manager, save and
modify the resulting job. At least for t/F-contrasts where one can
specify a contrast vector per session, it should be fairly easy to
modify the batch.
Hope this helps,
Volkmar
