Using a sequence of "b0" models doesn't currently work

[arokem]

Using:

models = ("b0", "b0")
...

em_affines = estimator.fit(
        dwdata=dwi_motion, align_kwargs=None, models=models, seed=None
    )

results in an error:

No such file or directory: '/home/tmgomez/eddymotion/src/eddymotion/config/dwi-to-b0_level1.json'

Is there a particular way to pass a sequence of models that avoids this? Or maybe we are not intended to use the "b0" model more than once?

I didn't care to write ANTs parameters for a second level - but we probably want to have this for consistency.
