ANTsPy: Registration, how to code convergence value ?

[flo-mingo]

Hello!

I'm looking for a way to add a convergence value in my registration parameters. Could it be in kwargs ? or somewhere else ?
You can see below an exemple of my transform, and I would like to set the convergence value to 0, but couldn't find a way.
Thanks !

mytx = ants.registration(fixed=MRI_ants_mask, moving=IHC_ants_mask, type_of_transform='Affine', aff_sampling=2, metric_convergence_threshold=0, aff_iterations=(200, 100, 100, 20), aff_shrink_factors=(6, 4, 2, 1), aff_smoothing_sigmas=(3, 2, 1, 0), verbose=True)

Unfortunately, I don't think there's any way to set this in ants.registration
