Here is a typical structure for a batch script

1. Code to set up parameters across all the datasets 
   and do bits of analysis that are can be grouped
   

2. Loop over Subjects and Sessions 
    and perform the Main Crunch
   

E.g.

1. % reorientation, slice timing
   do_time_place5
   realign_spm5
   smooth_spm5
   
   % hp filter
   MYV.hf_cut = 60;
   

2. % Run models
   for sb = 1:length(MYV.subjects)
     for ss = 1:length(MYV.sesses)
       one_sub_sess_model_moves5(MYV, sb, ss);
       one_sub_sess_con_moves5(MYV, sb, ss);
     end
   end
   

Here

• do_time_place
  realign_spm5
  smooth_spm5
  one_sub_sess_model_moves5 (OneSubSess)
  

and

• one_sub_sess_con_moves5
  

are subscripts tailored to specialised parts of the sequence.
