Hi. For a relax_disp analysis Should I first run a: pipe.create(pipe_name='origin rx', pipe_type='relax_fit', bundle='rx') relax_disp.exp_type(exp_type='cpmg fixed') or a pipe.create(pipe_name='origin rx', pipe_type='relax_disp', bundle='rx') relax_disp.exp_type(exp_type='cpmg fixed') Best Troels Emtekær Linnet
