It seems that -input takes 2 parameters, not just 1.
Comparing to how I use it in slow_surf_clustsim.py,
you should just put a 0 after the -input dset, i.e.

-input 'lh.myData.niml.dset[11]' 0 \

Looking at the code, it seem that the 2 is not an index
into your list of options, but rather your option "2",
because it is reading -rmm as the second parameter
to -input. So I think the 0 will help.
