problem with creating ensemble members

[liuyiling_elaine@gmail_com]

I am trying to use ‘ pertlim' to create ensemble members. When I used branch runs, all created ensemble members were actually the same. Was it because ‘pertlim’ can only work  in ‘hybrid’ runs? My tests of using ‘pertlim’ by doing hybrid runs were successful. But the problem with hybrid runs is they are not bit-for-bit reproducible. Is there anyway to use branch runs to perturb initialistion states?
